JUDY WOODRUFF: Good evening.

I'm Judy Woodruff.

On the "NewsHour" tonight: President Trump raises doubts about the upcoming summit with North Korea during a meeting at the White House with South Korea's leader, Moon Jae-in.

Then: making sure a diploma means a future - - why Chicago Public Schools are requiring students to plan out their next steps before graduation.

And distraction-free entertainment -- how performers and venues are pushing crowds to live in the moment without their phones.

DAVE CHAPPELLE, Comedian: But I see how it distracts people.

Well, I used to make requests of the audience, could you not use your phone during the show?

And they can't honor the request.

JUDY WOODRUFF: All that and more on tonight's "PBS NewsHour."

(BREAK) JUDY WOODRUFF: There's new uncertainty tonight about President Trump's planned summit with North Korea's Kim Jong-un.

Mr. Trump met today with South Korea's leader, and said the meeting with Kim might be delayed.

That's after the North had threatened to cancel it.

We will have a full report after the news summary.

The president also talked today of a new way to penalize the giant Chinese telecom company ZTE.

Last month, the company was barred from importing American parts, after it admitted shipping U.S. technology to Iran.

In recent days, Mr. Trump suggested easing that ban.

Today, he floated a new plan.

DONALD TRUMP, President of the United States: What I envision is a very large fine of more than a billion dollars.

Could be a billion-three.

I envision a new management, a new board and very, very strict security rules.

And I also envision that they will have to buy a big percentage of their parts and equipment from American companies.

JUDY WOODRUFF: The president faces criticism in Congress, from both parties, that he's giving in to the Chinese government's pressure.

Palestinian leaders appealed today for the International Criminal Court to investigate alleged crimes by Israel.

They cited military killings along the Gaza border and Israeli settlement policies.

Israel called the action outrageous, and charged the Palestinians have incited the violence.

In Afghanistan, a blast in Kandahar killed 16 people, when security forces tried to dispose of a container full of explosives; 38 others were wounded.

Dozens of stores and homes were destroyed or damaged by the explosion.

The bombs were found in a cluster of car mechanic shops in the southern city.

Facebook founder and CEO Mark Zuckerberg confronted tough questioning outside the U.S. today.

He testified before the top European lawmakers in Brussels.

Andy Davies of Independent Television News filed this report.

ANDY DAVIES: It began with a handshake with the president of the European Parliament, who looked like he meant business.

And he went on to tell the Facebook boss that democracy can't be turned into a marketing operation.

And then, in the meeting with the Parliament's political leaders came Mr. Zuckerberg's familiar opening statement.

MARK ZUCKERBERG, Chairman and CEO, Facebook: We didn't take a broad enough view of our responsibility.

And that was a mistake.

And I'm sorry for it.

ANDY DAVIES: It was an apology in which someone in the room clearly knew it was coming.

GUY VERHOFSTADT, European Parliamentarian: The fact that maybe you have maybe less control or no control about your own company for the moment, because you have to apologize now.

I think, in total, you apologized now 15 or 16 times the last decade.

ANDY DAVIES: The format was a succession of questions first before a note-taking, listening Mark Zuckerberg, who gave the follow assurances on the recurring theme, fake news and the integrity of elections.

MARK ZUCKERBERG: In 2016, we were too slow to identify Russian interference on Facebook in the U.S. presidential election.

ANDY DAVIES: This week, European Union introduces its landmark general data protection regulation rules, or GDPR, whereby organizations will need explicit consent before processing E.U.

citizens' data.

MARK ZUCKERBERG: A number of you asked when we expect to be fully compliant with GDPR Regulations.

We do expect to be fully compliant on May 25.

ANDY DAVIES: Questioned, too, over concerns of political bias was influencing Facebook, he countered with this: MARK ZUCKERBERG: We will -- we have never and will not make decisions about what content is allowed or how we do ranking on the basis of a political orientation.

ANDY DAVIES: Next stop, Paris and a meeting with the French president.

JUDY WOODRUFF: That report from Andy Davies of Independent Television News.

The president of Venezuela has expelled the top U.S. diplomat in the country and his deputy.

Nicolas Maduro claimed today that they have conspired against his government.

The White House has called Maduro's election win on Sunday a sham.

Back in this country, Texas Governor Greg Abbott began a series of roundtables on school safety.

This follows Friday's shooting that left 10 people dead, eight of them high school students, in Santa Fe, Texas.

Abbot met today with school safety experts and law enforcers.

He will also speak with lawmakers, community leaders and victims.

The U.S. House gave final approval today to relaxing the Dodd-Frank banking law passed after the 2008 financial crisis.

The new law will ease rules on community and regional banks.

And on Wall Street, uncertainty over trade talks had an effect.

The Dow Jones industrial average lost nearly 179 points to close at 24834.

The Nasdaq fell 15 points, and the S&P 500 slipped eight.

Still to come on the "NewsHour": the high-stakes summit with North Korea now in question; a House Freedom Caucus leader on the divide in the GOP; Chicago, where passing grades is not the only requirement for graduation; and much more.

As we reported earlier, President Trump today voiced doubts about whether next month's planned summit with North Korea's leader, Kim Jong-un, would proceed as planned.

As Nick Schifrin reports, Mr. Trump and his South Korean counterpart met today at a crucial moment.

NICK SCHIFRIN: In the Oval Office today, President Trump blended a handful of hope with a pinch of perspective, hope that his planned summit with North Korean leader Kim Jong-un could create a historic peace.

DONALD TRUMP, President of the United States: He has a chance to do something that maybe has never been done before.

He will be safe.

He will be happy.

His country will be rich.

North Korea really has the chance to be a great country.

And I think they should seize the opportunity, and we will soon find out whether or not they want to do that.

NICK SCHIFRIN: And that perspective, that maybe the summit won't even happen.

DONALD TRUMP: There are certain conditions that we want.

And I think we will get those conditions.

And if we don't, we don't have the meeting.

There's a chance that it will work out.

There's a chance, there's very substantial chance that it won't work out.

That doesn't mean it won't work out over a period of time.

But it may not work out for June 12.

NICK SCHIFRIN: North Korea enters the summit presenting itself as a full-fledged nuclear state.

Whether and how the country denuclearizes is at the negotiation's core.

North Korean officials have expressed interest in slow, step-by-step denuclearization and step-by-step American incentives.

President Trump said today he'd prefer, but wouldn't insist, on swift denuclearization.

DONALD TRUMP: It would certainly be better if it were all in one.

Does it have to be?

I don't think I want to totally commit myself.

But all in one would be a lot better, or at least, for physical reasons, over a very short period of time.

NICK SCHIFRIN: The go-between for Trump and Kim has been South Korean President Moon Jae-in, who pushes peace in part by praising the president.

MOON JAE-IN, South Korean President (through translator): I have no doubt you will be able to accomplish a historic feat that no one has been able to achieve in the decades past.

NICK SCHIFRIN: Senior administration officials describe this moment to the "NewsHour" as brinksmanship between two men who don't want to be the one to cancel or be canceled on.

President Trump said his blend of hope and perspective comes from his past experience in business.

DONALD TRUMP: I have made a lot of deals.

I know deals I think better than anyone knows deals.

You never really know.

NICK SCHIFRIN: As of now, the administration continues to plan as if the summit will happen, but a senior official suggests that reporters who plan on going book refundable tickets.

We take a closer look now at today's meeting and the prospects for next month's summit with Balbina Hwang, who served in the State Department during the George W. Bush administration, and is now a visiting professor at Georgetown University.

And Jeffrey Lewis is the director of the East Asia Nonproliferation Program at Middlebury Institute of International Studies at Monterey.

He is also founding publisher of the blog Arms Control Wonk.

Welcome to you both.

Jeffrey Lewis, if I could start with you, why is President Moon of South Korea here?

What's his mission?

JEFFREY LEWIS, Director, East Asia Non-Proliferation Program, Monterey Institute of International Studies: I think he has one overriding mission, and that's to save the summit between President Trump and Kim Jong-un.

From President Moon's perspective, he wants to improve relations with North Korea, but he can't do that unless the United States is also doing the same thing.

So, if he wants what he wants, he has to get that summit to happen.

NICK SCHIFRIN: And, Balbina Hwang, is that right?

Is President Moon here to save the summit?

BALBINA HWANG, Georgetown University: Oh, absolutely, and not only.

President Moon has absolutely one mission, and that is actually to prevent war on the Korean Peninsula.

NICK SCHIFRIN: And trying to keep some of the rhetoric that we heard last year down.

I want to play some comments for both of you by the national security adviser, John Bolton, to FOX News about four weeks ago.

JOHN BOLTON, U.S. National Security Adviser: We have very much in mind the Libya model from 2003-2004.

There are obviously differences.

The Libyan program was much smaller, but that was basically the agreement that we made.

NICK SCHIFRIN: Bolton is talking about a deal about denuclearization from 2003.

But, of course, we know in 2011 he ended up dead in a ditch.

So, Jeffrey Lewis, what was Bolton's intention by bringing up the Libya model?

JEFFREY LEWIS: Well, you know, in his memoir, Bolton bragged about using diplomacy to actually advance other goals.

So he bragged about sending a delegation off to Pyongyang, feeling that he had sabotaged them and knowing that it would collapse.

My guess is that he was bringing up Gadhafi not because it really is a model for disarmament, but because he knew it would annoy the North Koreans.

And, in fact, it did.

I think we saw that the North Korean statement the other day singled Bolton out and made it very clear that Libya wasn't a precedent they liked.

NICK SCHIFRIN: Balbina Hwang, is that right?

Was the national security adviser perhaps trying scuttle this summit or somehow convince North Koreans that the U.S. wasn't serious about diplomacy?

BALBINA HWANG: Well, absolutely.

Libya is a red line that everybody knows is something that North Korea will not accept.

Now, on the other hand, it is also the sort of extreme that you set up going into negotiations, so that you know that that is the furthest line that you know that is the extent to which is the hard line, the extreme.

Now, we also know that President Trump is the negotiator.

That's how he presents himself.

That's how he is the deal-maker.

And when President Trump is going into the summit, that is what he says that he's going to do.

He's going to come out with a deal.

And so that is how he is going to go in, and that's exactly how he wants to set it up.

And so North Korea is obviously going to come out and say, we're not going to go into a summit with this kind of a deal.

So of course he's going to do that.

And I think that that's exactly how Bolton is setting this up.

NICK SCHIFRIN: So you're suggesting it actually could help, that this is something important, whether the U.S. public or for the U.S. simply to have this hard line going into the summit, that it's helpful?

BALBINA HWANG: Exactly.

NICK SCHIFRIN: OK. Jeffrey Lewis, should there be a summit?

We heard a lot of doubt about this today.

And what do you expect to come out of the summit if it indeed goes forward on the 12th?

JEFFREY LEWIS: Well, I think the answer to whether there should be a summit is, it depends, and I think it depends on whether the president goes in with realistic expectations.

I don't think the North Koreans are going to offer up their nuclear weapons.

I don't think that they're planning on disarming.

And so the real question is, are the North Koreans going to offer something short of that, a prolonged moratorium on testing missiles, a continued pledge not to test nuclear weapons, maybe a pledge not to export those technologies?

So you have to look at the likely North Korean concessions, what they're likely to put on the table and then ask, is that something you want?

The nightmare scenario for me is that John Bolton's counsel in private is not preparing the president for this, that he's getting him ready to expect a kind of surrender from Kim.

And when that doesn't happen, will the president settle for less or we will he throw a tantrum and walk out?

NICK SCHIFRIN: Balbina Hwang, should there be lowered expectations for the summit?

BALBINA HWANG: Well, is the summit really about the process of denuclearization and disarmament, or is the summit really about politics and is this really about a political process?

And I would argue that this really is about a political process, and if so, then, yes, there should be a summit.

And, possibly, there will be one.

NICK SCHIFRIN: Jeffrey Lewis, quickly, is there any risk in this summit to the U.S. alliance with South Korea?

JEFFREY LEWIS: Well, I think there is some risk.

You know, we're entering into this period where there are a lot of tensions.

President Moon is a progressive, but he's also quite nationalistic.

I think he's quite negative about the U.S. presence in the country.

And President Trump has insisted that South Korea pay more.

So my fundamental concern is, if the summit goes badly, we don't want a situation where President Moon decides that the big threat isn't Kim Jong-un; it's Donald Trump.

NICK SCHIFRIN: That's interesting.

Balbina Hwang, do some people in South Korea believe the threat is not Kim Jong-un, but actually Donald Trump?

BALBINA HWANG: I think this is the single biggest underestimated risk, is the alliance.

And this is the one thing that we are not looking at.

The whole summit is, unfortunately, played as between the United States and North Korea.

And what we're not looking at is the third actor, which is South Korea and the U.S. alliance with South Korea.

NICK SCHIFRIN: And, therefore, is there risk to this alliance, especially if the summit doesn't go well?

BALBINA HWANG: Absolutely.

That's right.

And, especially if the summit doesn't even occur at all, the alliance could be at risk.

NICK SCHIFRIN: All right.

Balbina Hwang, Jeffrey Lewis, thank you very much.

BALBINA HWANG: Thank you.

JUDY WOODRUFF: Conservative members of the Freedom Caucus in the U.S. House of Representatives called today for the appointment of a second special counsel to look into possible misconduct inside the FBI and the Department of Justice.

I spoke a short time ago with one member of the Freedom Caucus, Congressman Jim Jordan of Ohio.

You said today that you are -- quote -- "sick and tired" of the runaround you say you have been getting from the deputy attorney general, Rod Rosenstein, that you want a second special counsel appointed.

Why?

REP. JIM JORDAN (R), Ohio: Because Attorney General Jeff Sessions has stated that only under extraordinary circumstances do you have special counsels.

Well, how about the fact that five of the top people at the FBI have been fired or demoted and reassigned?

James Comey has been fired, former director of the FBI.

Deputy Director Andrew McCabe has been fired.

There is actually a criminal referral because he lied three times under oath, according to the inspector general.

Deputy Director of Counterintelligence Peter Strzok has been demoted and reassigned.

FBI counsel Jim Baker has been demoted and reassigned.

FBI counsel Lisa Page has been demoted and reassigned.

Five of the top people demoted, reassigned, and in some cases fired from the FBI, if that isn't unusual, if that isn't extraordinary, someone define to me what is.

And these five people, while they were working in the Obama administration, ran the Clinton investigation and then launched the Russia investigation into President Trump and his campaign.

They're the ones who did the dossier.

They're the ones who maybe were involved in what we have seen, this possible informant issue.

So, for all those reasons, it warrants a second special counsel.

JUDY WOODRUFF: Well, as you know, Congressman, the deputy attorney general is a Republican appointed by this administration.

The head of the FBI, Christopher Wray, a Republican, appointed by this administration.

Why not have confidence in them, let them finish.. (CROSSTALK) REP. JIM JORDAN: Judy, I don't care if they're Republican, Democrat, independent, Martian.

I don't care.

What I care about is getting the information.

We have asked repeatedly for information.

Repeatedly, they have denied.

And we have actually caught the Department of Justice in withholding information.

One of the text messages between Peter Strzok and Lisa Page talked about the relationship Peter Strzok had with the FISA court Judge Contreras, who also happened to be the judge who heard Michael Flynn's case.

They redacted that.

They didn't want us knowing that somehow Peter Strzok and Judge Contreras were friends.

Why?

What does have to do with -- so, when you catch the FBI -- or -- excuse me -- the Department of Justice withholding information from Congress, for no good reason, that sort of puts everything else under this cloud and a little suspect, as we look at it.

JUDY WOODRUFF: Do you think they have lied to you or misled you?

REP. JIM JORDAN: I know they have redacted that portion of the text message from Strzok and Page, between Strzok and Page, that talked about the relationship Mr. Strzok had with Judge Contreras.

They redacted that.

Why?

Is that classified?

No.

Is it part of an ongoing investigation.

No.

They just didn't want us to know, and for some reason it was redacted.

So, that's been the history.

They have told us we're entitled on the Judiciary and Oversight Committee to approximately 46,000 documents.

Over the last 6.5 months, we have received approximately 15,000.

JUDY WOODRUFF: Right.

REP. JIM JORDAN: At the pace we're going, we're going to be well into President Trump's second term before we ever get the information that they have told us we're entitled to as members of the separate and equal branch of government.

JUDY WOODRUFF: But if this doesn't happen quickly, just quickly, Congressman Jordan, are you prepared to honor the work that the special counsel is doing?

REP. JIM JORDAN: No one is talking about the special counsel.

We're just talking about getting information.

But what we do know, now, think about this.

Those five people who have been fired, demoted, or reassigned, those same five people took an opposition research document paid for by the Clinton campaign, took it to the FISA court to get a warrant to spy on a fellow American citizen.

They didn't tell the court who wrote the document, that that guy who wrote the document had been fired by the FBI, Christopher Steele, and they didn't tell the court who paid for it.

JUDY WOODRUFF: Well, they have... REP. JIM JORDAN: When I go to court, Judy, when we go to court, we have to tell the whole truth, nothing but the truth, all the truth.

But the FBI went to court and didn't do the same thing.

That's a problem.

JUDY WOODRUFF: I want to move on to something else.

Inside the Republican Caucus, in the House of Representatives, there are clearly serious divisions.

Republicans didn't support the GOP leadership, what the GOP leadership wanted last week with regard to the farm bill.

Is Speaker Ryan in trouble?

Should -- do you believe that he's going to see out his term as speaker until the end of... (CROSSTALK) REP. JIM JORDAN: There's plenty -- I do think that - - Paul has been clear about that.

There's plenty of time to get a farm bill done.

We do want to get a farm bill across the finish line, one that actually has work requirements for folks in the SNAP program, the food stamp program.

But, right now, the focus is on getting immigration policy right, because the American people, on November 8, 2016, were very clear about making sure we built the border security wall, we did the right thing on immigration.

That's what we conservatives are focused on getting done, because that was a paramount issue in the last campaign.

JUDY WOODRUFF: But I'm also asking you about the leadership.

Since this was a -- basically a repudiation of what the leadership was asking for, are we now looking at a situation where Speaker Ryan's job is in jeopardy?

REP. JIM JORDAN: It wasn't a repudiation.

It was saying we should have a focus on doing the right immigration policy.

After all, some of our colleagues are... JUDY WOODRUFF: Well, that's not what the leadership... REP. JIM JORDAN: ... putting -- are bringing forth a discharge petition, which would bring to the floor, and the end result would be a bill that is not consistent with the mandate of the 2016 election.

We're focused, we conservatives who oppose that farm bill, we are focused on getting the right immigration policy done, one that is consistent with what we told the American people we were going to do.

JUDY WOODRUFF: And, finally, Congressman, more than 100 members of the Tea Party movement have signed a letter urging you to run for speaker of the House.

Are you going to do that?

REP. JIM JORDAN: I have been very clear, if and when there is a race for speaker, I plan to be a part of that conversation.

Right now, the focus has got to be on what we do as Republicans to make sure we're in the majority.

If we -- more important than who the speaker is next year is what Republicans do this year.

We better get focused on the things the American people elected us to do, accomplishing those things.

And first and foremost in that is the right kind of immigration legislation that deals with the border security wall, deals with chain migration, deals with the visa lottery.

That's what we have got to focus on.

JUDY WOODRUFF: Should there be a new election for speaker before the election?

REP. JIM JORDAN: No, I think the speaker has been clear he's going to stay until after the election.

And I think that's just fine.

JUDY WOODRUFF: Congressman Jim Jordan of Ohio, thank you very much.

REP. JIM JORDAN: Thank you, Judy.

JUDY WOODRUFF: And for more from both ends of Pennsylvania Avenue, I'm joined now by our White House correspondent, Yamiche Alcindor, and by Lisa Desjardins at the Capitol.

Welcome to you both.

So, Lisa, we just heard from Congressman Jordan, not only about the special counsel, but the other thing he's asking for is that the Justice Department release a trove of classified documents, turn it over to Congress.

What is the conversation on Capitol Hill about that?

LISA DESJARDINS: I think, as you got out of Senator -- or out of Congressman Jordan, there is a real concern from some conservatives that the FBI abused its power.

However, Judy, from other Republicans and some conservatives, there are two other worries, one, that those conservatives are going too far too fast.

They say let the inspector general of the Department of Justice, who is working on this issue, finish that investigation.

The other concern is even broader, Judy -- and I heard this on both sides of the Capitol today from Republicans -- a worry that this is changing the rules of the game, how classified intelligence is handled.

They're worried that by allowing some members who may complain in some cases to have access to this kind of information, that it sets a very bad precedent.

Also, there are concerns that only Republicans are invited to look at -- to talk about this information this week, not Democrats.

Usually, these things are bipartisan.

JUDY WOODRUFF: So, Yamiche, let's pick up on that.

The president has asked his chief of staff, General John Kelly, to work on setting up meetings, to talk about these documents, what should be released.

What have you learned about that?

YAMICHE ALCINDOR: Well, President Trump is one year into making the case that he's a victim of overreaching by the Department of Justice, and these documents and the arguments about them really are being used to build that case.

President Trump said that he -- in a meeting today, when asked, he said that he wanted to kind of get to the bottom of this, that the Congress wants to know.

But, essentially, it's that Republican lawmakers want to know.

And I want to read off some of the people that are going to be on that -- in the meeting.

It's going to be FBI Director Christopher Wray.

It's going to be the director of national intelligence, Dan Coats.

It's going to be Representative Trey Gowdy and Chairman Nunes.

And what we see there, of course, is not just any kind of Republicans.

What we see there are people who have been making the case that this president is a victim of really a political campaign to get him out of office and for people who don't like him.

So I think it's really important to not just think about the fact that there are no Democrats there, but the Republicans that are there are people that have been very vocal supporters of the president.

JUDY WOODRUFF: So, almost a foregone conclusion going in.

YAMICHE ALCINDOR: Yes.

JUDY WOODRUFF: Lisa, different subject.

As we know, more conversation today about where the trade talks stand with China.

Several strands to that, the conversations both at the White House and at the Capitol.

What are you hearing about that?

What are lawmakers saying?

LISA DESJARDINS: This was one of the topics that came up the most today.

And it started this morning with a tweet from Senator Marco Rubio, a former opponent of the president's, this morning tweeting out that: "Sadly, China is outnegotiating the administration and winning the trade talk right now."

That's about as sharp of a critique as this president, who sells himself as a negotiator, as there can be.

Today, what's happened in Congress is, I hear from Republicans especially they're concerned that the president's policy on trade is scattered.

And, in fact, we saw today some actual action, not just words, Judy.

The House Banking Committee passed out of its committee a broad bill that would overhaul the way the U.S. looks at foreign investment.

It would in some ways make it tougher for Chinese investors and Chinese businesses that we think are security threats to get through.

In that bill, Judy, was a very specific amendment that would stop the president from being able to roll back sanctions on Chinese companies like ZTE.

That's the company that's been in the headlines lately -- and I think Yamiche will talk about it -- that the president has said he wants to help.

The Senate action today, Judy, went the other way and said to the president, no, you shouldn't be able to roll back these sanctions.

There is sort of a political war within the president's trade war.

JUDY WOODRUFF: Fascinating.

And, Yamiche, meantime, there are some reports today that the administration has reached some kind of deal with China over the ZTE question, which has been hanging out there, what, for 10 days now.

YAMICHE ALCINDOR: Yes, and the president when asked about it today said that there is no deal.

He said that he also is pushing back on criticisms that China is running circles around him.

The idea is that the president wants to make the case that he is being really, really tough on China, and that he says that the U.S. has been using -- has been losing for years, $500 billion a year, in Chinese trade.

So the idea is that this president is feeling like he has to be on the offense.

Today, Sarah Sanders was asked about this today, and she said Senator Schumer -- she pointed to Senator Schumer and said that his criticisms were very partisan.

But she didn't talk about the fact that Marco Rubio is also someone who is out there criticizing the president.

And what we see there is the president really feeling as though even his own party is questioning his leadership.

And they're trying to have a united front, trying to look strong, but there are obviously cracks in the way that these trade negotiations are happening.

JUDY WOODRUFF: Sounds like still a long way to go before this is figured out.

Finally, Lisa, something else going on at the Capitol.

The Senate has apparently come to some kind of an agreement on how to deal with sexual harassment claims inside the Congress.

Tell us about that.

You have been following this story and breaking news on it.

LISA DESJARDINS: That's right.

We at "PBS NewsHour" were among the first - - we were the first to learn today that there is a deal in the Senate.

After these many months of this question of the rules about sexual harassment in Congress being in limbo, waiting for congressmen to act on their rules, now there is a deal between Republicans and Democrats in the Senate.

A reminder that the rules here in the Capitol are just basically universally seen as archaic and unfair to those -- to victims of sexual harassment.

Currently, Judy, anyone accusing someone of harassment has to wait 90 days and go through forced counseling and mediation.

Here's what's in this deal in the Senate.

It would take away that 90-day delay, and it would make members of Congress personally liable.

They would have to personally pay for any sexual harassment findings against themselves for their behavior.

However, the Senate did make one change from what the House did.

Those members of Congress wouldn't be personally liable for their staff behavior.

So, we expect this to move forward pretty quickly.

It's taken a long time.

And this was a very big deal for people who work here in Congress and a statement from our lawmakers.

JUDY WOODRUFF: So, quickly, Lisa, that means they have reached final agreement?

LISA DESJARDINS: I wouldn't say final.

We have to wait for the votes, but, yes, every - - this has great momentum.

There are not any problems for it right now.

JUDY WOODRUFF: Lisa Desjardins at the Capitol, thank you for your reporting on that, Yamiche Alcindor, for all your reporting at the White House.

Thank you both.

JUDY WOODRUFF: Stay with us.

Coming up on the "NewsHour": a pushback against using cell phones during concerts; and "The Restless Wave," a new book from the maverick, Senator John McCain.

And now to our special look at Rethinking College this graduation season.

Our stories have been focused on programs that are helping lower-income students climb the ladder to economic stability.

Tonight, we head to Chicago, where there's a new plan to make sure kids pursue a college degree or have another viable career path after high school.

Hari Sreenivasan has the story.

It's for our weekly segment Making the Grade.

HARI SREENIVASAN: Students at North-Grand High School in Chicago know their teachers have high expectations.

BRETT MURPHY, Teacher: We have talked so much about GPA, and how every assignment and every class counts.

HARI SREENIVASAN: But, on this day, freshman seminar teacher Brett Murphy upped the ante.

BRETT MURPHY: The class that has the highest overall GPA as a whole will get to shave my head right here in the middle of the classroom, sitting in a chair.

HARI SREENIVASAN: A high school on academic probation just five years ago, North-Grand's new focus on raising grades has transformed them into a top performing school, even before teacher Murphy decided to have fun with the idea.

BRETT MURPHY: The first person will take an electric razor and zoom it across my entire head.

The next student will come up here and lather my head up with a bunch of shaving cream.

HARI SREENIVASAN: North-Grand High principal Emily Feltes: EMILY FELTES, Principal, North-Grand High School: The idea of freshman seminar came because we wanted to help our kids learn how to do high school successfully, so really getting them into this mind-set of, college is possible, I am capable.

HARI SREENIVASAN: The seminar is part of a new citywide strategy to get students prepared for life after high school.

It's called Learn, Plan, Succeed.

By 2020, in order to get a diploma from Chicago Public Schools, a student will have to prove that they either have a job, will be joining a trade school, will go on to college, or join the military.

RAHM EMANUEL (D), Mayor of Chicago: High school degree doesn't cut it anymore.

HARI SREENIVASAN: The idea came from Chicago's Mayor Rahm Emanuel.

RAHM EMANUEL: You just have to show either a letter from college, a letter of acceptance from a branch of the armed forces, or a letter of acceptance from a trade school.

That will give to us the confidence that you have a plan for the future.

You're not just dropping off the cliff on high school graduation day.

HARI SREENIVASAN: Is that the responsibility of the city of Chicago?

RAHM EMANUEL: It's a responsibility to the kids of the city of Chicago, yes.

HARI SREENIVASAN: North-Grand senior Joshua Zayas was accepted at eight schools.

Neither his parents nor his older brothers went to college.

JOSHUA ZAYAS, Student: Their high school didn't really push them to excel to the next level.

Here, like, it's a requirement.

HARI SREENIVASAN: But Zayas has reasons beyond the district's expectations.

Last year, his 19-year-old brother, who he says took the wrong path, was shot and killed.

JOSHUA ZAYAS: Seeing where he dropped out, and how his life went, that was something that actually motivated me not to do.

I honestly don't want to struggle.

Like, that's my thing.

I just don't want to struggle.

I want to have my career and I'm set, happy, home and... HARI SREENIVASAN: Should the city be worried about what happens after graduation?

EMILY FELTES: I think it's a moral imperative to be worried about what happens for our children after graduation.

The old days of we have got you graduated out of high school are done.

HARI SREENIVASAN: According to Janice Jackson, the CEO of Chicago Public Schools, 60 percent of high school students already meet the graduation requirement.

JANICE JACKSON, CEO, Chicago Public Schools: The other 40 percent, that's the group that we're most concerned about.

What we're trying to do is ensure that the students who need it the most are the ones that are receiving the support.

HARI SREENIVASAN: There's going to be people that say, listen, you just moved the goal line for what constitutes a diploma.

A child has worked their 12 years, they should get this piece of paper without having to tell you what two more years looks like.

RAHM EMANUEL: I didn't move the goalposts.

The economy did.

Companies today are looking for somebody with a minimum of something post-high school.

HARI SREENIVASAN: Critics of Chicago's plan question if cash-strapped schools will be able to provide the support and guidance a student needs to meet the new requirement.

Kristy Brooks is a school counselor and represents counselors for the Chicago Teachers Union.

KRISTY BROOKS, School Counselor: My main concerns are that we're not resourcing that plan.

We need more counselors in our schools, and we need funds for that.

HARI SREENIVASAN: Brooks wants the city to limit the student-to-counselor ratio and stop asking school counselors to perform duties that are outside their role as advisers.

KRISTY BROOKS: Chicago Public Schools ranks 28th out of 30, on the very low end of counselor-to-student ratios.

Principals have to allow counselors to actually do counseling work with kids.

We can't be pulled to be counting tests all the time.

We can't be pulled to do recess duty and lunch duty three hours a day.

Mayor Emanuel has been under fire by teachers and neighborhoods for closing dozens of schools.

HARI SREENIVASAN: Do you have enough counselors?

JANICE JACKSON: I don't think it's a situation where you need more counselors.

I think we have to look at some of the duties that counselors have, and maybe relieve them of some of those.

HARI SREENIVASAN: This spring, the mayor tapped employees from its vast community college system to assist counselors and students with the new requirement.

RAHM EMANUEL: By integrating the community college system, we're ensuring an integration, that kids do not fall between the gap between high school and graduation and whatever else they do in life.

HARI SREENIVASAN: But some ask if the new advisers have the qualifications needed.

KRISTY BROOKS: What are their credentials?

Are they certified?

School counselors hold master's degrees and licenses.

Do they know our kids?

We get to know our kids.

HARI SREENIVASAN: At North-Grand High School, principal Emily Feltes made the decision to hire more qualified school counselors.

But, to do so, she had to forgo some classroom technology, like computers and smartboards.

EMILY FELTES: The ratio is lower, and we have a full-time college coach.

Not all schools are as fortunate or are in that shape.

HARI SREENIVASAN: And at North-Grand, some freshmen already had plans for their future.

JAYVON COOPER, Freshman: Once I get my degree, to be a professional basketball player.

SANDRA VALENCUELE, Student: To be a culinary chef.

ASHLEY CARRASQUILLO, Student: Study to be a veterinarian.

HARI SREENIVASAN: But others remained skeptical that the new requirement was a good fit for all students.

CHERVERIS THOMLINSON, Student: At our age, we're still young, and still figuring out what we want to do with our life, so I think we should have more time to figure out where we want to go with our futures.

HARI SREENIVASAN: What's the scenario where a student can't meet these requirements and doesn't get a diploma?

JANICE JACKSON: That -- I'm telling you that scenario won't happen.

I'm not saying this just out of hope or aspiration.

We intervene before it's too late.

HARI SREENIVASAN: In Chicago, for the "PBS NewsHour," I'm Hari Sreenivasan.

JUDY WOODRUFF: These days, it's hard to go to a concert or show where people don't quickly pull out their smartphones to capture the moment or let their friends know that they're there.

But some artists and performers have had enough of that.

Jeffrey Brown tells us about a start-up that is catering to that sentiment, and its ambitions for dialing back our phone use in a much bigger way.

JEFFREY BROWN: A recent concert at the famed Fillmore Auditorium in San Francisco, filled with music and laughs.

But note something missing: no smartphones held high capturing the proceedings.

That's just the way comedian Dave Chappelle wants it.

DAVE CHAPPELLE, Comedian: But I see how it distracts people.

Well, I used to make requests of the audience, could you not use your phone during the show?

And they can't honor the request.

JEFFREY BROWN: They can't?

DAVE CHAPPELLE: Oftentimes, they cannot.

Grown, responsible, disciplined adults have a hard time watching a comedy show without the distraction of their phone.

We all need a break, just from the technology, just for a minute.

JEFFREY BROWN: Chappelle is part of a growing movement of comedians and musicians pushing back against the ubiquity of the smartphone in the concert hall and in our lives.

DAVE CHAPPELLE: The phone is an addictive device.

I don't know if you have ever lost your phone.

Like, just the anxiety you feel, it's almost like worse than losing a pack of cigarettes or something else that's addictive.

JEFFREY BROWN: Here in high-tech central, with Silicon Valley nearby, companies large and small vie to produce and monetize the latest gadgets.

But one local start-up, called Yondr, is after something different, prying them away, at least for a few hours.

Thirty-one-year-old Graham Dugoni is its founder.

GRAHAM DUGONI, Founder, Yondr: It's just going hey, here's a phone-free show, here's a classroom.

Here's an event, or a wedding.

You step into this space.

While you're there, what happens there stays there.

It's socially acceptable to unplug.

Your nervous system can relax from kind of the call-and-response pattern of modern life.

JEFFREY BROWN: It's deceptively simple: At large events, a Yondr team passes through the line, takes your phone and puts it in a locked pouch, which you get to hold onto.

At the end of the night, your pouch is unlocked.

If you really need to use your phone, there are spaces available, a bit like smoking areas at the airport.

Dave Chappelle likes the idea so much, he's become an investor in Yondr, which charges a fee to the performers or venues, not the phone users.

Some 400 artists and musicians have used Yondr so far.

But, for Dugoni, Yondr is as much a cause as it is a business.

GRAHAM DUGONI: And I think people are looking for new ways to kind of -- to live, and things that can center their lives.

I see us as just part of that, creating a real, functional, practical sense, just creating - - by helping people create device-free spaces.

JEFFREY BROWN: In the age of social media, people are experiencing art in new ways.

Exhibitions like the recent blockbuster by Japanese artist Yayoi Kusama come Instagram-ready.

"Wired" magazine editor Arielle Pardes has written about art and technology.

ARIELLE PARDES, "Wired": So, it's not just the show that the artists put on for you, but it's actually you taking that, capturing it, remixing it, posting it on your Instagram account, and turning that into your own version of art.

JEFFREY BROWN: Yes, so the art that's on the wall or the music up on stage no longer lives by itself?

ARIELLE PARDES: Exactly.

And I think artists are a little bit squeamish about that, understandably so.

A lot goes into creating art.

JEFFREY BROWN: In today's music world, social media cuts both ways.

In part, it's a marketing device.

At most of his concerts, guitarist and singer John Mayer allows smartphones, which help get the word out about his music.

JOHN MAYER, Musician: If that's how you want to enjoy the show, I get it, because we -- I also have a phone in the dressing room, and I will go do something at night and take a picture with it.

JEFFREY BROWN: In your career, though, you have watched that take off, that technology and evolution.

JOHN MAYER: Yes, sure.

But it's helped me.

I can also promote things from bed.

JEFFREY BROWN: But when performing with Dave Chappelle, as on this night, Mayer abides by other rules, and likes those too.

JOHN MAYER: It's become unconscious thinking now that, when you sing something on stage in front of people, and you have a bad note, you go, well, that's going to make the tape.

I'm working something out.

Dave is working something out.

Sometimes, that has to be cumulative.

I learned last night, OK, I messed up the chorus in my own song that I just wrote.

I don't have to suffer the indignity of knowing that that lives in repetition in 50,000 views.

JEFFREY BROWN: People in line at the Fillmore seemed happy enough to play along.

MAN: It's cool.

Like, you want to do something and you don't want everyone watching every single imperfection of a new performance, it's cool.

WOMAN: You paid like a significant amount of money to go see the performer.

So, you should see the performer.

MAN: I'm not that guy that is taking pictures of the act.

I'm going to experience that and just let it be right here.

WOMAN: People don't have that self-control, so I am all for it.

Lock it away.

Lock it up.

JEFFREY BROWN: And Yondr is now being used in other places, at weddings, for example, including Serena Williams', and in courtrooms and more than 1,000 schools, like West Potomac Academy in Northern Virginia, where teacher Nancy Mantelli is happy to have her students' full attention.

NANCY MANTELLI, Teacher: In my opinion, cell phone use is a mental health issue, because I feel that the students are addicted to it.

They simply can't put the phone down.

So, here I am as an educator, and I'm trying to give them this neutral environment, a safe environment to teach them.

And that cell phone puts them right back into that place where they're potentially being bullied, where they're getting harassed.

JEFFREY BROWN: All this raises new questions, of course: Does locking up a phone limit free speech?

Who gets to decide what's a phone-free zone, especially in a world where cameras can help monitor and expose bad behavior?

Yondr founder Dugoni: GRAHAM DUGONI: What is the interplay between privacy and transparency in modern society?

And the answer is, in a way, it's complicated.

I think that's part of a healthy, ongoing dialogue in a well-functioning society, is to understand that there are choices.

But, if you think, if anyone thinks endless transparency is going to lead to more freedom, I think that's naive, because it leads to - - it's a prison of its own.

JEFFREY BROWN: And technology itself changes, like these recently released sunglasses that capture video, potentially outstripping efforts like Yondr.

ARIELLE PARDES: I see it as a bit of a cat and mouse game.

Yondr is sort of fixing the problem of the iPhone, but what about what comes next?

JEFFREY BROWN: For now, though, Dave Chappelle thinks it's keeping the focus where it belongs.

DAVE CHAPPELLE: It's also about the quality of the performance.

And we always have this feeling of being lucky like, we're an us.

And us in this room, we're the only ones who get to see this or feel this.

Or you're not thinking about outside the room or anything, and it is kind of wonderful now.

JEFFREY BROWN: Something to think about for those on and off the stage.

For the "PBS NewsHour," I'm Jeffrey Brown in San Francisco.

JUDY WOODRUFF: Republican Senator John McCain is known as a maverick, familiar with tough fights, from prison camps in Vietnam to the floor of the U.S. Senate.

Recently, he has been staying close to the Arizona ranch he calls home, as he undergoes treatment for brain cancer.

But he still speaks his mind.

And there are new glimpses this month into McCain's life and thinking.

He and his family are part of a new HBO documentary, "John McCain: For Whom the Bell Tolls," which debuts next Monday.

Here's a look.

SEN. JOHN MCCAIN (R), Arizona: Come on, Verma (ph).

Come on, honey.

JACK MCCAIN, Son of John McCain: I got a phone call from my mom that said: "Jack, you're going to see some stuff in the news.

Your father has brain cancer.

I'm with him right now.

He knows his diagnosis, and he's the same as he's always been.

He said, 'All right, let's push forward.'"

SEN. JOHN MCCAIN: You know, these doctors keep talking to me about people who, if you tell them the truth, and then they just give up and die, that you really want to -- and I keep saying them, just tell me.

Just tell me.

That's all I want to know, you know?

Some say, well, it's not good.

And I say, well, you know it's just (EXPLETIVE DELETED) and it really drives me crazy.

But then I talk to other doctor friends of mine and say that most people, that's not what they want to hear.

Why wouldn't they want to hear, you know?

Why wouldn't they want to spend a few more days here, you know?

JUDY WOODRUFF: McCain's battle with cancer is also ever-present, whether explicitly or implicitly, in a new memoir out today.

There are reflections about living and past decisions, but it also makes clear that McCain still has plenty to say about America, American society, and politics in the age of President Trump.

It is called "The Restless Wave," and McCain co-wrote it with one of his close longtime aides, Mark Salter, who joins me now from New York.

Mark Salter, thank you for being with us.

Give us an update on how... (CROSSTALK) JUDY WOODRUFF: Thank you -- how Senator McCain is doing.

MARK SALTER, Co-Author, "The Restless Wave: Good Times, Just Causes, Great Fights, and Other Appreciations": He's hanging in there.

He's fighting, working hard at getting stronger.

He had an operation a couple weeks ago that knocked the wind out of him a little bit.

But he's back home, and he's working on getting stronger and still staying engaged with his office and doing all the things he wants to be doing right now.

JUDY WOODRUFF: You have been writing books with him for, what, almost 20 years.

This is your seventh book together.

MARK SALTER: That's right.

JUDY WOODRUFF: This book sounds like -- it reads like he's still got a lot rolling around in his mind that he wants to get out there.

Restless wave, what did he mean by that?

MARK SALTER: Well, it's a line from the Navy hymn "Eternal Father."

It refers to eternal father, strong to save, whose arm hath bound the restless wave.

And most people know who know John McCain know him to be a very restless individual, and only God can restrain him.

So, we thought that was an appropriate title, under the circumstances.

JUDY WOODRUFF: But a lot to get off his chest in this book.

MARK SALTER: He did.

The book -- we had started working on the book before his diagnosis.

And it was a little bit different of a book.

It was going to concentrate mostly on foreign affairs and national security.

But he wanted to write something more personal and tell stories about the causes that matter most to him and to write about what America means to him and what America means to the world.

JUDY WOODRUFF: Well, one of the many things he writes about -- he rally covers his entire public career -- he writes about choosing Sarah Palin as his running mate in 2008.

He takes responsibility for any of the problems in that campaign and her role in it, but he also says that he wishes he had chosen Democratic Senator Joe Lieberman as his running mate.

How much does that bother him?

MARK SALTER: Well, I think that was his first choice.

He wanted to do it.

He was persuaded by his aides and from senior members of the party that it would cause a divided convention and a challenge perhaps on the floor to the nomination of his vice presidential pick, and was convinced not to do it.

He would have -- looking back, he wished he had stuck with it.

That's not to say he regrets choosing Governor Palin.

There is a distinction there.

And I think people have mixed that up a little bit.

But it's not.

Once he decided or was convinced that he couldn't pick Senator Lieberman, he chose Governor Palin, and he never regretted it publicly or privately.

He's never said a word of regret about it.

JUDY WOODRUFF: He writes at some length about how much he has loved serving in the Senate.

He makes that very clear.

His friendships across the partisan aisle.

Why has that been so important to him?

MARK SALTER: Well, he served there for over 30 years now, a long time.

And even before that he was the Senate's -- the Navy's Senate liaison officer.

And he got to know some of the lions of the Senate back in the '70s, Scoop Jackson, Barry Goldwater, John Tower, traveled with them overseas quite a bit, had bipartisan friendships, became good friends with some of the then younger members, Gary Hart, Bill Cohen, Joe Biden.

And he's just -- it's a place that he's seen do enormous amount of good and work together collaboratively to make progress on the problems of our time, something that he's worried is getting a little lost now.

JUDY WOODRUFF: On the -- moving around, there's so much in this book, Mark Salter.

At one point, he does write about getting a copy of the so-called Steele dossier, the report written by the former British intelligence agent Christopher Steele, turning it over to then-FBI Director Comey.

It is clear that he takes the Russia interference in the last election seriously.

What does he think about how other Republicans see that?

MARK SALTER: Well, he thinks most of his colleagues in the Senate take it pretty seriously.

I'm sure he's been a it a little -- like many people who worry about Putin and Putin's challenge to the U.S. and his challenge to American allies, he probably worries a little bit about some people in the House Intelligence Committee not taking it that seriously.

But he takes it seriously.

He's had a pretty good sense of Putin.

Going back all the way to the late '90s, he has been warning about him.

So, he thinks probably China is our long-term challenge, you know, over the next generation or the work, but our immediate problem is Vladimir Putin.

And he would like the see members of Congress in his party and the Democratic Party confront that challenge honestly and forcefully.

JUDY WOODRUFF: So much of this book, or at least a good chunk of it, reads like what he is standing up -- what he stands for is in opposition to what President Trump stands for.

He talks about being a champion of compromise, being someone who believes in working with the other side, and toning down the harsh rhetoric.

And let's air just a little bit of what he himself read from the audio version of this book at the end.

MARK SALTER: Sure.

SEN. JOHN MCCAIN: Before I leave, I would like to see our politics begin to return to the purposes and practices that distinguish our history from the history of other nations.

I would like to see us recover our sense that we are more alike than different.

We're citizens of a republic made of shared ideals, forged in a new world to replace the tribal enmities that tormented the old one.

Even in times of political turmoil such as these, we share that awesome heritage and the responsibility to embrace it.

Whether we think each other right or wrong in our views on the issues of the day, we owe each other our respect, so long as our character merits respect.

And as long as we share, for all our differences, for all the rancorous debates that enliven and sometimes demean our politics, a mutual devotion to the ideals our nation was conceived of hold, that all are created equal, and liberty and equal justice are the natural rights of all.

JUDY WOODRUFF: Mark Salter, that's a very different message from what's in the political atmosphere right now.

Why did he want to get that out?

MARK SALTER: Well, you know, he has served in uniform and in public office.

He's served this country for 60 years, quite a long stretch of time.

And serving this country to him has meant serving her ideals, to see them advance in the world and to see them safe here at home.

That's been the most just cause of his life, and a cause that he believes has given his life honor and purpose.

So, he is obviously concerned when he thinks that we're losing sight of that, that we're - - whether it's, whatever you call it, nativism or America-first nationalism, that is only concerned about getting what advantages there are in the world for us, and to hell with the rest of humanity.

I don't want anyone to think, and he wouldn't want anyone to think that this book is just an anti-Donald Trump diatribe.

It's not.

They have differences on many issues that are very important to the senator, and he discusses those issues quite forthrightly.

But the book is about a great deal more than that.

It's about his love of this country and what it means to him and what it means to the world and what he hopes it will continue to mean to the world in the future he may not be here to see.

JUDY WOODRUFF: How many of his Republican colleagues in the Senate does he think share those views?

MARK SALTER: The vast majority of them.

JUDY WOODRUFF: But why aren't we hearing from them, does he think?

MARK SALTER: Oh, I think you do.

And they do -- a lot of the work -- you know, it's always the controversies that get all the attention, for obvious reasons, but take a look at the committee he chairs, the Armed Services Committee.

That -- every year, year after year, that committee reports out its bill, the defense spending -- authorization bill, almost always unanimously, always in a bipartisan fashion.

Everybody works collaboratively, with a sense that American -- America's leadership of the world is important to us and important to the world.

That doesn't get as much attention as noisier, more confrontational or controversial statements and actions on the part of some members of Congress, but it's more the norm than not.

JUDY WOODRUFF: Is he hopeful for the country's future?

MARK SALTER: He believes -- yes, he believes this country is a match for its challenges in the present and in the future.

JUDY WOODRUFF: Mark Salter, who wrote the book with John McCain "The Restless Wave: Good Times, Just Causes, Great Fights, and Other Appreciations."

Mark Salter, we thank you.

MARK SALTER: Thank you, Judy.

Appreciate it.

JUDY WOODRUFF: And that book is out today.

On the "NewsHour" online right now, we have live video of the dramatic eruption at the Kilauea volcano summit in Hawaii.

You can watch that and more on our Web site, PBS.org/NewsHour.

And that's the "NewsHour" for tonight.

I'm Judy Woodruff.

Join us online and again here tomorrow evening.

For all of us at the "PBS NewsHour," thank you, and we'll see you soon.
