department in advancing their own personal agenda? >> no. i don't know if he knows who the sources are in our story. but the only thing i'd point out is that in our story, we say that a spokeswoman for the justice department provided us with a background statement from someone that was in the room who said that rosenstein had said this. they don't contest the fact that he had said this but that it was done sarcastically. and that is in our story but as we pointed out earlier, the -- rosenstein was asked in the meeting whether he was kidding. and he said he wasn't. that's where we ended up on our reporting and we feel comfortable. rosenstein is in a very difficult spot where he has to explain why this happened. in many ways, he sees himself as the protector of mueller. so i guess that's where we end up with this statement.
