MCCASKILL: Here’s what I have to say about Bill Barr. I'm glad that he talked to the authors of this book. but this is not going to work for him. He was a hack attorney general. He was an attorney general that gave a short shift to the rule of law and to the norms that this country expects when it comes to separation of politics and the Department of Justice.

He did this president's bidding in unspeakable ways and if you don't believe me, you ask the line prosecutors in the Department of Justice. You ask the people who were undercut by Bill Barr when he did ridiculous things like trying to undo a guilty plea of one of Trump's henchmen.

So, I am really - have little patience for Bill Barr. If he wants to do the country a favor, then I think he needs to come out of the shadows, he needs to do a full-blown interview and take some of the questions about why in the world he would reverse a guilty plea of a criminal, why in the world he would do this president's bidding. And yeah, he walked away at the end. I'm sorry it doesn't do any good for me. I could care less he walked away at the end. What a jerk.
