Two separate blasts rattling nerves at this hour. And a driver entering an american base, reportedly briefing the main gate, then crashing. Reports of possible propane tanks inside and an explosion. Good evening. And its great to have you with us here on a thursday night. And we begin with major turbulence on wall street and inside the white house. The president s lead personal attorney general on the russia investigation suddenly resigning, and tonight, word of a new National Security adviser. Also tonight, the president taking dramatic action on china, right there, signing his order for tar riches on imports from china. Well, then, the dow plummeted, down 724 points, fears of retaliation now from china. A possible trade war. We have it all covered, beginning with that search for a new lawyer, and a new National Security adviser. The tweet from the president just moments ago. Heres abcs chief White House Correspondent jonathan karl. Reporter with his legal team in turmoil, the president today said he actually wants to answer questions from special counsel robert mueller. Mr. President , would you still like to testify to special counsel robert mueller, sir . Sure. I would like to. I would like to. Reporter just this just after the president lost his lead attorney on the russia investigation, john dowd, the man negotiating the terms of an interview. In fact, dowd met with mueller just last week. But today, he quit. Sources familiar with their relationship tell abc news dowd felt the president wasnt taking his advice. They had been at odds for a while, first over the mueller interview itself. Trump told us back in january he was eager to do it. Are you going to talk to mueller . Im looking forward to it, actually. But i would love to do that, and id like to do it as soon as possible. Reporter but that night, dowd told abc news that he, not the president , would decide if mueller got the interview. At the same time, dowd counseled the president not to criticize mueller. Not to even tweet the special counsels name. Advice the president ignored, tweeting this weekend, why does the mueller team have 13 hardened democrats, some big crooked hillary supporters, and zero republicans . While mueller has hired several democratic lawyers, he himself is a republican. Perhaps in a bid to encourage the president to leave the attacks to his lawyers, dowd put out his own statement over the weekend, calling on the Deputy Attorney general to end the russia investigatiinvestigation quote, follow the brilliant and courageous example of attorney general jeff sessions, who had just fired deputy fbi director andrew mccabe. Dowd added the investigation was, quote, manufactured by mccabes boss, james comey. Today, a very different sort of statement from dowd. I love the president and wish him well. As for the president , if any of this was troubling him, he wasnt showing it. Rattling the financial markets, he announced his intention to impose punitive tariffs on china to fight back against chinas unfair trade practices. If they charge us, we charge them the same thing. Thats the way its got to be. Reporter shortly after that, he shared this light moment with a group of young conservatives. What advice do you give to the 25yearold donald trump knowing what you know today . Dont run for president. Reporter the president went on to say he got great Media Coverage before his campaign. Now, he says, thats all changed. So, lets get to jon karl, live at the white house tonight. And jon, the lead personal attorney general resigning. This leaves a big vacancy.

All right, jon karl with the breaking news, just as we come on tonight, thank you. And as i mentioned, the president s other muse today on china led to major jitters on wall street. The dow plummeting today, closing down 724 points. So, lets get right to Rebecca Jarvis tonight. What happened . Reporter thats right, david.

It doesnt look so much like there was a concert there, but that a tornado swept through there. Those overturned lawn chairs, weve seen strollers there, weve seen walkers there. Evidence of just the absolute chaos. What the video couldnt show is how paddock rigged his room. His own surveillance cameras under that plate, the barriers on the door, the hammer he used to shatter the window in his snipers perch. And finally, his lifeless body among the bullet casings. Matt gutman with us again tonight. And matt, the hotel is releasing the very say lens, saying that it shows howl paddock was able to blend in without raising red flags . Reporter thats right, david.
