moment. appearing to push aside the prime minister of montenegro to get in front for a photo-op. and as for those allies he spent the campaign offending -- >> nato is obsolete. it's old, it's fat, it's sloppy. >> reporter: president trump later changed his mind. but today, instead of making nice, he scolded them. >> nato members must finally contribute their fair share and meet their financial obligations. >> reporter: he told them the united states spends more on defense than all other nato countries combined, and now it is time to pay up. >> 23 of the 28 member nations are still not paying what they should be paying, and what they're supposed to be paying for their defense. this is not fair to the people and taxpayers of the united states. >> reporter: some leaders serious, others whispering to each other. canada's justin trudeau, stone faced. germany's angela merkel throwing out a subtle jab of her own, saying it is trust, not walls, that unites.

president trump also face to face with the new president of france, congratulating emmanuel macron, whose far-right opponent many likened to trump. >> congratulations, great job. >> reporter: their handshake seeming to go on and on. >> thank you very much. >> cecilia vega with us from the sicily. the g7 is next. president trump could face some tough questions. >> definitely, david. we just touched down here and this one is not going to be easy for him, either, those world leaders are looking to press president frump on everything, from trade to climate change to america's policy on refugees. david. >> cecilia vega in sicily thank you. to a contentious moment right here at moment. voters at the polls today. overnight the republican candidate allegedly throwing a reporter to the ground. you'll hear the moment as it played out. the candidate has now been charged. a fox news crew witnessing the whole thing, saying it did

happen. but tonight, voters at the polls have two very different takes. abc's clayton sandell is in bozeman. republican greg gianforte, the frontrunner in montana's special election, was about to do an interview with fox news. that's when ben jacobs, a reporter for "the guardian", tried asking a question. >> in terms of the cbo score -- because, you know, you were waiting to make your decision about healthcare until you saw the bill, and it just came out. >> we'll talk to you about that later. >> yeah, but there's not going to be time. >> reporter: the reporter recording it all. >> i'm sick and tired of you guys. the last guy that came in here did the same thing. >> get the hell out of here. >> the last guy did the same thing. are you with "the guardian"? >> yes, and you just broke my glasses. >> the last guy did the same damn thing. >> you just body slammed me and broke my glasses. >> get the hell out of here. >> he grabbed the recorder, and the next thing i knew i went from being vertical to horizontal on the floor. >> reporter: the campaign insisting he was just grabbing the phone that he said jacobs

pushed in his face. "it's unfortunate that this aggressive behavior from a liberal journalist created this scene. >> reporter: but the fox news crew said he wasn't the aggressor. >> i did see the whole thing when gianforte grabbed him by the neck, both hands, slid him to the side, body slammed him and then got on top of him and started punching and then yelling at him. >> reporter: today, gianforte nowhere to be seen -- cancelling appearances, his headquarters dark. and voters we talked to today were split. you didn't change your vote, why not. >> i don't think his, like, little stuff really affects -- >> i don't think mr. gianforte is ready for politics. >> reporter: the hotly contested race seen as a test of support for the president, who just yesterday was praising gianforte in this robocall to voters. >> he's a wonderful guy. he knows how to win, he's going >> and clayton with us live in

bozeman. regardless if he's elected to congress, paul ryan saying this candidate owes an apology. >> yes, he did. paul ryan said that he should apologize to voters but he also said voters here in montana should decide his fate david. >> okay, clayton, thank you next this ening to the breaking headline late today involving president trump's second try at a travel ban. tonight an appeals court deciding the ban will remain on hold. at issue was this question -- should donald trump's words as a candidate matter now as a candidate. abc's mary bruce on the hill tonight. >> reporter: david, this all comes down to the president's own words. his call during the campaign for a muslim ban now seems to be coming back to haunt him. today, the 4th circuit ruled that the president's order to limit travel ban will remain on

hold. it speaks with vague words of national security, but in context drips with rry religiou. this is big setback for the president. they plan to appeal to the supreme court. next tonight to that deadly suicide bombing in manchester, the concert with american pop star marco rubi >> reariana grande. was he scouting the mall abc's terry moran. this new image tonight in retrospect so sinister. salman abedi taking out the garbage cans at his suburban home, wearing a traditional hooded north african robe and sandals. and today, these haunting security camera images of abedi, at a shopping mall just three days before the attack, baseball cap pulled down, apparently carrying the same backpack he used in the bombing. he spent his final night here, in a rented apartment just two

miles from the arena, phoning his mother in libya to say, "forgive me." today, more police raids across the region, and in the town of wigan, clearing the neighborhood after bomb technicians moved in. police desperately trying to unraffle a terror network. they call this the "curry mile" in manchester. it's the heart of the muslim community here and a very welcoming place, but within two miles of this spot, and the surrounding neighborhoods, 16 young men over the past couple of years have committed acts of terrorism. but the people here say abedi and the others don't represent them. >> terry moran with us live from manchester. police today have found several key pieces of evidence in those raids? >> reporter: to that's right, authorities say the police investigation is hitting paydirt, important evidence, suspicious items today, significant arrests, four men charged with terrorism offenses tonight.

investigators are rolling up a terror network they didn't know about. >> terry moran our thanks to you back here at home and to the severe weather, major disruptions to airports in the northeast. after at least 25 reported tornadoes in just the past two days. the latest this massive cloud swirling in franklin, ohio, one of four confirmed tornadoes in north carolina ripping off the roof of this home and all of this as millions of americans begin travel for the memorial day weekend. abc's linzie janis at laguardia airport. >> it's comin' this way. >> look at that tornado. >> reporter: tonight, the system that dropped some two dozen reported tornadoes in six states now on the move. snarling travel for millions of families getting a jump-start on their holiday weekend. delays and cancellations piling up at major airports. >> we're two hours delayed so far. >> reporter: that rain already triggering flash flooding across the ohio valley. outside dayton, a traffic camera

david. >> travel safely to everyone. rob, our thanks to you. next tonight the high school under fire after a student killed himself. school officials confronting him about what they thought was on his phone. they called his mother, but she arrived too late. abc's alex perez. >> reporter: school officials scared the teen so much he committed suicide. >> they threatened him and scared him to the point where this fine young man thought his life was over. >> reporter: according to court documents, in january, walgren was called into the dean's office at naperville north high school after a 16-year-old and school officials brought him into the office and demanded he turn over the phone. allegedly threatening saying he would have to register as a sex

offender. >> they're required by state law to do an investigation. >> reporter: they called his mother and say they wanted to download on what was his phone. >> i need to be there in person. >> reporter: his mom was racing to the school but corey left that school office before she could arrive. >> at this point, i didn't know he was alive or not. but i just knew that he was dead. i just knew it. >> reporter: a distraught teenager jumped to his death from the fifth floor of this building and that recording the school sought turned out to no clear images. david the school here says they're investigating the tragedy. but in the statement the city of theirville said confident the school resource officer followed proper procedures. alex, thank you an abc news investigation.

civilians, only some of which can be broadcast. this is happening all the time? >> this is happening all the time. >> reporter: this man, he says, was a sheep herder, whose teenage sons were suspected of working for isis. >> there's not even a pretext here of torture in the name of obtaining intelligence. this is just torture for fun. >> reporter: sadistic? >> sadistic. >> reporter: in a remarkable phone call with us, the unit captain, omar nazar, admitted the video was real and said he was proud of what was on the tape. "i'm already a star and ali would make me a bigger star by doing this." the soldiers were so proud of what they were doing they even sent arkady horrific phone videos they shot themselves, the victims they tortured and murdered. >> i don't even have words for it. >> reporter: that's a murder, isn't it? >> that's a murder. >> reporter: in a statement, the american embassy in baghdad told abc news the u.s. "has not provided military aid, arms or assistance" to the unit.
