In an interview with CNN "New Day" host Brianna Keilar, the Washington Post's Bob Woodward explained that his researcher has uncovered evidence that could be used in a conspiracy charge against Donald Trump and some of his closest allies.

Speaking with the CNN host, Woodward explained, "[Co-author] Robert Costa and I didn't discover this, but our assistant who is a lawyer, Claire McMullen, is just bombarding us with research and information. And she discovered on May 5th, John Eastman, in a podcast -- now, this is before our book came out -- specifically talked about the war room and the Willard [hotel] and said it was kind of coordinating all of the communication."

"Then in a very important legal point he said I would not normally talk about things like this, but I have been directed by the president of the United States -- at that time that was Trump, to tell and to talk -- so he's waived the privilege," he continued. "And traditionally judges will look at this and say, 'Hey, wait a minute, you're out talking about it, but also you're saying your client, the president of the United States specifically said talk, explain,' so how do you justify not talking to this committee or a grand jury and so you're kind of -- you've got one and a half feet in the door already."

"It is really fascinating," Keilar interjected. "The Willard, for the uninitiated, the Willard Hotel in Washington, D.C., it is near the White House and he's referring to this war room, this kind of coordination center that we heard Steve Bannon actually refer to before as well."

"I do want to talk about Michael Flynn," she continued. "You've reported extensively about some of what Michael Flynn has said that is obviously very interesting to this committee and that has to do with his discussion of invoking martial law."

"Yeah, he is the hard-liner in the Trump orbit," he replied, "and would be a key witness in this. Now, as we have discussed, the January 6th committee does not have a strong hand because there will be delaying moves and traditionally congressional committees can't get this kind of information and this goes back to the Nixon tapes case in 1974. So this is in the hands of the Justice Department and, again, Claire, our assistant, has been saying, 'look, go back and look at the Supreme Court decisions.' This is a clear case of a violation of what is called 371 Section conspiracy to defraud the U.S. If this is not a conspiracy to defraud the U.S., I don't know what is."
