Transcript for Big takeaways from Robert Mueller's 1st public remarks
Mary, thank you. Let's bring in Dan Abrams. Our chief joust 'tis correspondent Pierre Thomas and, Pierre, let me begin with you. Robert Mueller could have simply put out a two-sentence statement saying I'm going back to private life but chose to make this statement. Why did he do it? Reporter: George, it seems clear to me based on my sources that Mueller after all this time wanted to speak for himself in his own words and talk about his conclusions. So that the world could hear him. It wasn't lost on him or his team that he had hasn't spoken in two years an made a point of saying he chose his words carefully in that report and that he was doing so yesterday as well and so while the president has said that he was exonerated on the obstruction of justice issue, Mueller went out of his way to state again if it was clear the president had not committed a crime, he would have said so. That said, Mueller again was true to form. He does not want to testify before congress because he said his report speaks for itself and in effect that is his testimony, full stop and he wants to fade back into silence again at least on that subject. George, another point emphasized by sources last night is that Mueller wanted to make it abundantly clear how serious those attacks by the Russians were and that it must be addressed as something that all Americans should be concerned about, in short, it was not a witch-hunt and finally he wanted to stand by his staff, people he said had the highest integrity, George. That's how he closed the statement. Let's bring it to Dan Abrams. 440-page report boiled down to nine minutes. Very interesting. The few major points that Robert Mueller chose to make. Well, it's clear Robert Mueller thinks that the report was misinterpreted. He wouldn't have felt the need to go out and talk again about Russian interference. I mean there are two in-depth indictments of Russians that if you read, you will see how serious the Mueller team believes that that Russian interference was. He again focuses on the fact that there is another body out there that can hold the president responsible and it is not the criminal justice system. It is the congress. It is, again, he's focusing on obstruction of justice and all of the reasons he laid out in his introduction to that section, it was almost as if he was saying, it feels like a lot of people didn't read my report, because everything he said was in the report. Part of the reason for that is that William Barr went out and said as he was giving the summary that he on his own made the determination the president did not obstruct justice. Correct, and I think there is no way to reconcile what Barr is saying with what Mueller is saying. Barr saying they can be. Barr is saying it's not inconsistent. It's hard to look at those two statements and say these are consistent with one another because Barr gave a summary of what Mueller said and in particular when talking about how important was this issue of a sitting president not being able to be indicted and throughout Barr's either testimony or when he was talking publicly, he sort of minimized that, sort of saying, no, you know, that really wasn't as far as I know the big issue, yet, according to Robert Mueller it was the issue. And now it's all up to congress. Dan Abrams, thanks very much.
