cooperating, doesn't that suggest that robert mueller has a bigger fish in mind that he needs michael flynn's cooperation for? >> alisyn, thanks for having me. and it does suggest that he is working his way up the chain. in my years as a criminal defense lawyer before i was ethics czar, i often cut these deals. invariably, alisyn, the prosecutors wanted my client, in order to get cooperation, to flip on somebody up the chain. in this case, that means kushner, don jr., or perhaps the president himself. >> renado, i mean, for a while the thinking was maybe michael flynn was the biggest fish. he is the person with all sorts of russian ties that we had seen on video or in photos. so this has changed the equation.
