you would hope congress would get on its own without having to dig through mueller's trash. not having to go back through what he's already done. they're at that point. they have not been able so far to get don mcgahn and hope hicks to testify. you have to look at the clock, the election coming up. i remember heading into mueller day, we said the bigger testimony would be mcgahn. he was the cooperative witness. he talked to mueller over 30 times. he was at the heart of the obstruction accusations. he was the one the president talked to to fire mueller, and then he said tell everybody i didn't tell you to fire mueller. is he at the heart of that. he is what all of this could switch on. >> you watched that first hearing, don mcgahn's name came up question by question. laying out the obstruction case
