The victims from las vegas speaking out this evening after news mgm, the owner of the mandalay bay hotel, is now suing more than 1,000 victims and their families. And the images that have many talking today, the demolition accident. The building suddenly collapsing in a cloud of dust. The mayor tonight saying, quote, something went terribly wrong. Good evening. And its great to have you with us here on this monday night. And we have several stories were following just as we come on the air tonight. Were going to begin with the president and that unprecedented warning shot, that threat to strip security clearances from several former highranking officials in the cia, the fbi and u. S. Intelligence. Among them, former cia director john brennan, former fbi director james comey and four former Top National Security and intelligence officials. Sarah sanders today reading from a carefully scripted statement. Our terry moran then asking the white house, is the president threatening to punish these figures because they have been critical of the president . And what the white house then said when asked if former president obama and Vice President joe biden could be next. Abcs terry moran leading us off from the white house. Reporter an unprecedented threat from the white house podium. Press secretary Sarah Sanders reading from a prepared statement, announcing that President Trump was preparing to strip security clearances from some of the fiercest critics of his approach to russia. The fact that people with security clearances are making these baseless charges provides inappropriate legitimacy to accusations with zero evidence. Reporter sanders mentioned six highranking former National Security officials, including former fbi director james comey, former obama National Security adviser susan rice and former cia chief john brennan, who blasted Trumps Press Conference with vladimir putin. I use the term that this was nothing short of treasonous, because it is a betrayal of the nation. He is giving aid and comfort to the enemy, and it needs to stop. Reporter brennan has even seemed to hint darkly that he knows secrets harmful to trump, tweeting in march, when the full extent of your venality, moral turpitude and political corruption becomes known, you will take your rightful place as a disgraced demagogue in the dust bin of history. All this enrages trump. The president is threatening to punish brennan and comey and clapper for saying things about him that he doesnt like. Is that president ial . Theyve politicized and, in some cases, actually monetized their Public Service and their security clearances. And making baseless accusations of improper contact with russia or being influenced by russia against the president is extremely inappropriate. Reporter so theyre when we have further updates on that front, ill let you know. Reporter their free speech, he doesnt like. And he wants to punish them for it. Ah, no, i think youre creating your own story there. The president doesnt like the fact that people are politicizing agencies and departments that are specifically meant to not be political. Reporter two of the people on the president s list, comey and his former deputy, andrew mccabe, already lost their clearances awhile ago. Sanders was then asked, who is next . What about president obama and Vice President biden . Are their security clearances are they on the list, as well . Im not aware of any plans for that at this point. Reporter the president s move today comes as hes under fire for repeatedly questioning the intelligence communitys conclusion that russia attacked the 2016 election. Last week, under pressure, he tried to change course. I accept our intelligence communitys conclusion that russias meddling in the 2016 election took place. Reporter but then, once again, he seemed to dismiss the idea of a russian attack as a hoax, tweeting over the weekend, so, president obama knew about russia before the election. Why didnt he do something about it . Why didnt he tell our campaign . Because it is all a big hoax. Sanders doing more cleanup today, insisting the president believes that russia interfered in 2016. She says the hoax is the allegation that trump conspired with the kremlin. Just part of what we were following from the white house today. Terry moran live at the white house. And terry, were also following the growing tension between the u. S. And iran. As you know, President Trump tore up the Nuclear Agreement some time back. But over the weekend, we witnessed strong words from irans moderate president , hasan rouhani, warning the u. S. That peace with iran is the mother of all peace and war with iran is the mother of all wars. But terry, as youve been reporting all day, that invoked an angry response from President Trump. Reporter it did. An angry response in all caps. The president tweeting at president rouhani, never, ever threaten the United States again or you will suffer consequences the likes of which few throughout history have ever suffered before. Be cautious. And then today, the foreign minister of iran trolling President Trump, responding in all caps, color me unimpressed. But even more important than that, he called the president s words bluster and referred to the way the president talked about north korea, challenging President Trumps credibility on this issue. David . Terry moran on a monday night. Terry, thank you. Were also following new developments coming in just moments ago after that deadly mass shooting in toronto.

I felt like if i was able to get a life jacket, i could have saved my babies. Reporter but she says the captain told passengers they wouldnt need the vests. Regulations require life jackets, or pfds, to be onboard, but the decision to don those pfds is made as an operational decision for the captain onboard. Reporter investigators recovering the boats data recorder, which may provide clues to how the crew responded, and answers for grieving families. Since ive had a home, its always been filled.
