if people don't want to cooperate? >> well, with regard to someone like mark judge or others, that's a place where you could run into some problems. it is not required to talk to an fbi agent. it would be purely voluntary. if mark judge or others would refuse to talk to the fbi agents, the remedy really is to go back to the senate and ask them to issue a subpoena for their testimony before the committee. in light of the short time line that has been put on this, one week, i don't know that if someone refuses to cooperate they could get them subpoenaed and appear before the committee in that short period of time or in they would have the political will to do so, so far mark judge has said he is willing to cooperate. if i were brett kavanaugh and i believed i was innocent and really wanted this confirmation, i would urge all my friends to talk with the fbi. so that's really the remedy is a subpoena, but we'll see whether the chairman has the political will to issue one. >> as they say the fbi is your friend if you're telling the truth. i could not ask for two better or more learned guests to come
