what they're doing. they're just gathering their case, building their case. with time, we'll know what it's all about. but the white house trying to discount it and discredit it, is really playing a risky game. >> we've learned that the former white house chief strategist, steve bannon, was questioned by robert mueller's team over the period of two days. that happened this week. how big of a piece of the puzzle do you think that steve bannon is? >> again, he has a lot of knowledge once he comes into the campaign. he comes in the last 90 days. so he knows what was happening then. and he certainly knows what was happening as they got the white house off the ground. those were the times when the decision was made to fire comey. that's when flynn was in jeopardy and doing some back-channel dealings with the russians. that might have been okay if he'd have done them openly, but he didn't.
