Back in this country, the house of representatives moved to address puerto ricos debt crisis. A bipartisan bill will create an independent financial control board and restructure some of the islands 70 billion in debt. Supporters, including republican jim sensenbrenner, said its the only option. Lets get puerto rico back on track. And this is a way to do it with some help from the Oversight Board. Puerto ricans are going to have to do this themselves. They havent been able to do it without a tap on the shoulder. Too bad theres an Oversight Board but thats the only game in town. Woodruff Minority Leader Nancy Pelosi and other democrats also backed the bill. But some conservatives complained it amounts to a federal bailout. Others, like democrat luis gutierrez, whos of puerto rican descent, argued it takes too much authority from local officials. Let me suggest to you, if you give power to a control board unelected and unsupervised by anyone here. Be careful. Be careful. Remember flint. Remember the poisoning of the people. What the control board did there. That is exactly we should suspect will happen. Woodruff puerto rico has a 2 billion debt payment thats due on the first of july.

Still to come on the newshour whats next for Bernie Sanders after president obama endorses Hillary Clinton. The secretary of Homeland Security talks Long Airport Lines and terrorism threats. Making sense of why power corrupts, and much more. Woodruff today president obama made it official, endorsing secretary Hillary Clinton to be his choice as the democratic nominee. The president also met with senator Bernie Sanders who didnt drop out, but did pledge to work toward party unity. We have our reporters at both ends of pennsylvania avenue tonight, political director Lisa Desjardins on capitol hill, and john yang at the white house. So, john, the president was all in today, wasnt he . Absolutely, judy. His aides say he cant wait to get back out on the campaign traivment even though senator sanders wants to fight on for the final primary, its clear the delicate dances for the Fall Campaign are underway. Tens of millions of americans have made their voices heard. Today, i just want to add mine. Reporter the president made his formal declaration in a web video look, i know how hard this job can be. Thats why i know hillary will be so good at it. In fact, i dont think theres ever been someone so qualified to hold this office. Reporter within minutes, clinton tweeted her response honored to have you with me. Im fired up and ready to go all of this, not long after the president met with Bernie Sanders at the white house. The vermont senator emerged to say hell press on through next weeks washington, d. C. Primary. He again declined to endorse clinton, but did promise every effort to beat the republican nomineetobe. I look forward to meeting with her in the near future, to see how we can Work Together to defeat donald trump, and to reporter the other outstanding question for Many Democrats how to get sanders to stand down without offending his base. Senate democratic leader harry reid met with the candidate this afternoon. Of course, hell be involved in the process of what goes on in coming up with party platform, and elections in the future. Hes not holding out for anything, other than what he believes is principled. He goes out of way in praising sanders as in a taping for nbcs tonight newshour shw it was a healthy thing for the Democratic Party to have a contested primary. I thought that Bernie Sanders brought enormous energy and new ideas, and he pushed the party and challenged them. I thought it made hillary a better candidate. Reporter in todays endorsement video, mr. Obama added a nod to sanders legions of youthful voters. There are millions of americans, not just democrats, whove cast their ballots for the very first time. And a lot of that is thanks to senator Bernie Sanders, who has run an incredible campaign. Reporter while sanders ponders his next move, the president will join Hillary Clinton on the campaign trail, for the first time, in green bay, wisconsin, on june 15th. Significantly that event is the day after the final contest, the d. C. Primary. Tonight sanders kicks off his d. C. Campaign with a big rally. Judy . Woodruff looks like the white house, the president put a lot of thought, took a lot of care in how they dealt with Bernie Sanders here at the end. Today they say Bernie Sanders has earned the right through what ehs done in this Campaign Season to end this campaign on his own time, on his own schedule. Theyre giving him the space to do that. That endorsement video was taped tuesday here in the residence of the white house. The plan was always to release it sometime after the meeting and the indications are that the meeting went better than expected, and they actually moved up the release. Judy . Woodruff we know the thinking is among Many Democrats that its really important they treat standards well because of whats hes brought to the party. They really do. You will notice in all the comments, hes really been praising sanders for bringing young people in, firsttime voters. They want him to keep that up, to keep those young people in the fold so that theyll vote for Hillary Clinton in the fall. Woodruff all right, john at the white house. Lets turn to Lisa Desjardins whoas at the capitol. Lisa, you have been talking to a lot of folks up there. Theyre watching this closely, werent they . They are, judy. An important endorsement is expected tonight. The boston globe and others report Elizabeth Warren is planning to announce her endorsement of Hillary Clinton tonight, her voice so important because sanders voters may respect her voice somewhat more than the president s. Tonight democrats feel not just relief but move right into exuberance, almost. Some saying if they can unify the clintonsanders camps, they have a shot at major gains here at the cal capitol. Woodruff Bernie Sanders was as we know the democratic socialist member of the senate from the state of vermont. Hell come back to the senate in a different place, wont he . How do members of the Senate Democrats see what hes done in this campaign . Democrats here in the senate, i talked to senator dick durbin earlier tonight and he says he feels Bernie Sanders played a key role in marking the important part of the democratic identity. Democrats tonight in the senate are both figuratively and literally embracing Bernie Sanders, Chuck Schumer giving him a hug. One of my colleagues reported seeing him earlier tonight. They want him to feel that they respect him and that hes a powerful figure. All that said, of course, judy, questions remain as to whether he will get what he wants at the convention, all this good support and nice talk, what does it bring Bernie Sanders in the end . Thats a question for us to watch. One other anecdot up here at the capitol, judy, republicans, meanwhile, they are not following the kind of choreography we saw from democrats today. I ran into ted cruz coming alone from the senate floor today, asked if he heard from the Trump Campaign and said, pause, i decline to comment on that. So not unity on that on the Republican Party front. Woodruff i wanted to ask you about that quickly, lisa. Republicans are not volunteering much now about donald trump . No, i put in a lot of phone calls to republican members and one after another they told me we actually dont want to talk about donald trump right now. Theyre in a very difficult position and they know it. Woodruff Lisa Desjardins at the capitol, john yang at the white house on a momentous day here in washington. Thank you both. You got it. Woodruff the First Official day of summer is just around the corner, but the Summer Travel season is well under way, and travelers at major airports across the country are enduring record wait times at security checkpoints. Meanwhile, travel warnings have been issued for americans heading to europe, over fears of terrorist attacks there. All this comes as the threat of terrorism here at home persists. Joining me now to discuss all this, is the man who oversees Homeland Security. Secretary jeh johnson. And mr. Secretary, we can withum. Thanks for having me, judy. Woodruff so what is the status of security screening at american airports right now . We heard so much about it, about the problems a week or so ago. First, we are not going to compromise Aviation Security in order to expedite wait times, in order to shortcut wait times. Were going to keep passengers moving but were also going to keep them safe. So beginning last year, we began to really take a hard look at Aviation Security and refocus our efforts, and we knew then that it would lead to longer wait times for a lot of travelers in the busiest airports. Couple that with the travel volume were seeing this summer, and that has led to the wait times in some of the nations busiest airports at particular times of the day, like the situation in chicago ohare a couple of weeks ago. Right. In the meantime, weve brought on to fulltime status a lot of t. S. A. Officers that you see at the airport, we authorized a lot of overtime for them, using more canine teams and right now we have pending in congress a request to do what we call reprogramming of more money to bring on more and convert more parttime to fulltime t. S. O. S which will add to the screening capability and lower the wait times. Woodruff how did it get to this point . T. S. A. Is what, now, 15 years old. We have rededicated ourselves to Aviation Security in response to the world situation, frankly. That is something that i directed t. S. A. To do about a year ago. That has led to added wait times, and you couple that with the increased travel volume were seeing, and it has led to some of the very long lines in the nations busiest airports. When you say rededicate yourself to yourselves at Homeland Security to figuring out what the problems are in dealing with them, does that mean you found deficiencies well, as a lot of people know last summer, there was an inspector generals report that, unfortunately, leaked that revealed certain flaws in a specific type of screening that we conduct at certain airports, and that required us to take a real hard look at Aviation Security. So the new t. S. A. Administrator took office on july 6. I swore him in and gave him a tenpoint plan for rededicating ourselves to Aviation Security in reaction to that i. G. Report and the world situation that were seeing with some of the challenges across the globe. So the administrator has implemented that, and that has added to the security at screening checkpoints. In addition to that, you have, of course, the brussels attack where what the terrorist did was attack the area outside the secure part of the airport. What has that meant here in the u. S. . We have been focused on Airport Security now for almost two years, really. Weve directed continuous random screening of airport and airline personnel. Weve reduce number of Access Points to sterile areas through which Airport Airline employees pass. But in general, an airport, before you go through security, is a public area, just like a train station, just like a bus station, just like an athletic event. So there we feed to work with local authorities, Airport Security, to ensure that travelers are safe when theyre in these public places. We mentioned, as part of all this, that warnings have recently been issued to americans planning travel to europe, you know, in connection with the terrorist incidents over there. How concerned should americans be . My advice is americans should continue to travel. They should continue to travel during the summer months but be vigilant, be aware, Pay Attention to state Department Advisories about particular countries, particular places, particular times. But in general, were not discouraging people from traveling but should Pay Attention to state Department Advisories. Couple of other quick questions about the terrorist aspect of all this. One of the criticisms that grew out of the attacks in brussels and paris is poor intelligence sharing between countries in europe, the members of the european union. How much of a problem is that and does that affect the United States . I think were moving in the right direction with your european allies. Ive spent a lot of time personally with my european counterparts, ministers of interior and those in the Law EnforcementIntelligence Community and we are seeing in gen
