He criticized the allies, again, for falling short on their share of defense spending. From brussels, special correspondent Ryan Chilcote begins our coverage. Reporter jets blazed over brussels and natos gleaming new headquarters this afternoon, the flags of all 28 Member States making a show of unity. But a short time earlier, with his fellow leaders looking on, President Trump renewed his longstanding demand nato allies must do more. Member nations are still not paying what they should be paying and what they are supposed to be paying for their defense. This is not fair to the people and taxpayers of the United States. And many of these nations owe massive amounts of money from past years and not paying in those past years. Reporter the president noted the bloc did however, shell out for that new home. I never asked once what the new nato headquarters cost. I refuse to do that. But it is beautiful. Reporter german chancellor angela merkel, speaking before the president , struck a different note in unveiling a memorial of the berlin wall. translated our alliance is united in the awareness of the importance to cooperate to insist on freedom and we are it is not isolation and the building of walls that make us successful, but open societies that share the same values. Reporter natos secretary general said the unveilings of the wall, and wreckage from the World Trade Center in new york, signify the importance of the alliance. We saw the strength of that bond after the 9 11 attacks hometown in new york and for the first time nato invoked our collective defence clause, article 5. One for all and all for one. Reporter mr. Trump did not explicity endorse article five, the first president who hasnt since the alliances founding in 1949. After calling nato obsolete last year, a comment hes since walked back, nato leaders seemed dismayed. President trump did, though, appear to push the Prime Minister of montenegro aside as the leaders moved through a hall. All of this, in a city that candidate trump called a hellhole last year. President trump has also criticized the european union, the other big institution headquartered in brussels, applauding britains decision to exit the bloc. The e. U. s two leaders who share the job of running the bloc of 28 countries the president of the european commission, jean claude juncker, and the president of the european council, donald tusk, also met President Trump today. Afterward, it was clear that differences remained. Some issues remain open, like climate and trade. And i am not 100 sure that we can say today, we means mr. President and myself, that we have a common position, common opinions about russia. Reporter the new american president also held his first meeting with frances newly elected president emanuel macron. The handshake lasted six seconds, and the 39yearold frenchman held his own. In private, he urged mr. Trump to respect the paris climate agreement. Finally, after a long day in brussels, the president flew on to sicily for the g7 summit tomorrow. Woodruff and a short time ago, i spoke with Ryan Chilcote, whos still in brussels. Ryan, welcome. So how did the european leaders react to President Trumps criticisms today . They have been very reserved, very guarded in their response to President Trumps criticism today. Dont forget that a good number of the leaders in fact, those that President Trump, i think, has been hardest on when it comes to their commitments to n. A. T. O. Are going to see him in sicily tomorrow, so they dont want a spat with President Trump. But, you know, they will clearly be very disappointed by the criticism today. A lot of them feel that the place where President Trump delivered his criticism was the wrong place to do it, beside this memorial that effectively was not just to u. S. Troops but also to n. A. T. O. Troops who have lost their lives in afghanistan fighting alongside the United States after n. A. T. O. Invoked article 5. So they dont like where the comments were made. Then the other issue, of course, is that many of them disagree that theyre not doing enough or moving in the right direction to support n. A. T. O. In terms of their military spending. The president pointed out that 23 out of the 28 n. A. T. O. Members are not spending 2 of their budgets on the military at this point of their g. D. P. , and they will say that, in fact, if you look at the commitment, they have until 2024 to do that, and here at n. A. T. O. , from the n. A. T. O. Officials ive talked to, they believe that the vast majority of the n. A. T. O. Countries are well on their way with verifiable plans to do that, with the notable exception of germany. But they werent showing that because they want to work with President Trump, and they clearly believe and that was very apparent in the body language today that this is a president that they need to win over. They need to assure him n. A. T. O. Is something thats in the United States interest. Woodruff very quickly, ryan. You were just in russia. You covered the kremlin 20 years. What do you think the russian officials are thinking about todays meeting . I wouldnt say they would be delighted about todays meeting because theyre never delighted by anything n. A. T. O. Does. They see fateo as a threat to russia. But they will be happier about this meeting than the meeting we saw last year or the year before. Remember, it was at those meetings n. A. T. O. Took a very hard line on russia in the aftermath of russias intervention in ukraine. It was those meetings that led to the deployment of about 3,000 n. A. T. O. Troops, troops under n. A. T. O. s command right at russias border in the baltic countries and poland. The fact that we didnt get that explicit expression of support from article 5 for President Trump today, these are the things the russians will be very pleased about. Woodruff any sense of what the trump delegation thinks about all this . They said the meeting was a success. Sean spicer spoke with reporters after and he said, you know, the president s hard line, if you will, the criticism he has been consistent with for the last year and a half is really paying dividends. He said the dinner meeting tonight started with a discussion about how the countries can share more of the burden, how they can participate in counterterrorism along with the United States, those have been two key demands from President Trump. Sean spicer, for one, played down the idea that President Trump should have explicitly supported or endorsed article 5, you know, saying, look, he was there to dedicate to read the dedication, to give this speech at a memorial that is called article 5 and 9 11, so, of course, the president even by just being here at the n. A. T. O. Meeting supports article 5. So he pushed back on that. They see the president s tough line at n. A. T. O. And europe in general as the right approach, the only way thats going to get the goods they want delivered. Woodruff Ryan Chilcote covering todays n. A. T. O. Meeting in brussels. Thank you. In the days other news, a federal Appeals Court in richmond, virginia, upheld a Lower Court Ruling that blocked President Trumps revised travel ban.

An estimated 45,000 people marched in the capital, brasilia, demanding that temer resign over corruption allegations. Police fired tear gas and pepper spray when some protesters set fires and vandalized government buildings. translated it does not represent the people, it is a movement created by unions, because to protest is correct but vandalism is totally wrong. What they did is an example of savagery. translated i approve demonstrations, but i thought the violence was absurd on both sides. Military police also made a serious mistake in targeting demonstrators. Woodruff temer initially said he called out troops, in a bid to restore order. He retreated today, after widespread criticism that it was a power grab. The f. B. I. Has declined, for now, to hand over documents on former director james comeys communications with the president.

Still to come on the newshour the Manchester Attack leaks from the investigation pause intelligence sharing. Fear of russia, sweden invests in its military as a precaution against neighboring russia, and much more. Woodruff its been a day for mourning in manchester, england, and for new police raids, in the concert bombing that killed 22 people. Police say they have very important clues to what drove salman abedi and to other potential suspects. Ciaran jenkins of independent Television News has our report. Reporter at 11 00 a. M. In the spring sunshine, manchester fell silent, united in grief. For a moment, remembrance outshone the darkness of terror. This was for the dead, the injured, their families and friends. Theyre closing in on his movements. On the night of the attack, he was in this rented Property Police raided yesterday. Police have made eight total arrests. This man was arrested. A property is searched tonight and two orthoproperties in manchester. Investigators face an unwelcomed obstacle. The New York Times published photos of bomb components from the last. The latest leak of last night the family Liaison Officer shared with those families the fact that intelligence had been leaked and published in the New York Times. It is absolutely understandable the distress and upset this has caused to those families who are already suffering as everyone can imagine.

Woodruff now we examine the diplomatic fight thats broken out over the leaked photos of the bomb detonated in manchester. William brangham takes it from here. Brangham british officials are so incensed over those photos being leaked that Police Stopped sharing information with the u. S. For a time today. Meanwhile, Prime Minister theresa may met with President Trump at the nato summit in brussels. Going in, she said britain wants to maintain its special Security Partnership with the u. S. That partnership is built on trust and part of that trust is knowing that intelligence can be shared confidently and i will be making clear to President Trump today that intelligence shared between Law Enforcement agencies must remain secure. Brangham the president , in turn, issued his own statement condemning the leaks. He asked the Justice Department and other agencies to launch a complete investigation. For more on this, and the larger investigation into the bombing, im joined now by ali soufan. Hes a former f. B. I. Special agent who handled several major terrorism investigations, including the 2001 alqaeda bombing of the u. S. S. Cole in yemen. He now runs a Consulting Group and is the author of the new book antatomy of terror. Welcome back to the newshour. Thank you. Brangham from an investigators point of view, help me understand why the british would be so angry about these photos of these bombmaking parts. Why are those being out there would bother tell me so much . They have an Ongoing Investigation and this investigation is way more than an act that already happened. There is an imminent threat thats unfolding in the u. K. You want to protect your investigative leads, number one. You need to protect the integrity of your evidence, of your investigation, and when youre trying to catch terrorists who are still on the loose, you know, you dont want them to know what you know. So as an investigator, you know, and it happened to me personally, you get so frustrated when you see sometimes, intentionally or unintentionally, people hindering your investigation. So i dont blame the investigators on the ground to be really upset about leaks, about any investigative leaks that have been published either in papers or broadcasted on television. I am just not sure they can put all the blame on the United States. I think thats very unfair. I think, even in the pictures in the New York Times, i believe, in the New York Times story, they said they got access to them from british Law Enforcement sources. I think leaks are really bad in this situation. Its not only reckless, its dangerous when terrorists still on the loose, but to blame everything on the people here in the United States, i think its not fair. I think they need to do a further investigation to know whos leaking what to whom. Brangham just so im clear on this, the concern would be, lets just say the suspects in this case were to see those photographs. They would somehow know exactly what amount of evidenc
