this moment we have to document on paper. we don't know what all the other witnesses said in the mueller investigation. a question about are you on stage did you know about the trump tower meeting. who knows what the truth is going to come out and shake out as? these other witnesses may have told mueller something and if it doesn't jive with what is in that written statement they could go for a subpoena saying we need to clarify this and talk to him in person. >> help me understand the magnitude of that piece in the "new york times" about the conversations that the former white house counsel had with president trump, suggesting that hillary clinton should be prosecuted, james comey should be investigated. in this interview rudy giuliani said it's disgraceful she wasn't prosecuted. if anyone else did that they would have to go to trial. dove tailing those would things how important a moment is that? >> i constantly ask myself what it must be like to be don mcgahn in the white house.
