any fbi investigation, it is not in secret. you're asking neighbors, the fbi knocks on a neighbor's door and the fbi, people figure out, you're being investigated by the fbi. >> if the argument here, if the fbi were to investigate it, it would be tainted because the information has already come out. then surely a hearing without the benefit of any investigation is even more problematic. the notion here that the president could not pick up the phone and say, can you look further into this allegation? it just doesn't make sense. and the fact that it is public, she has made it public. that would mean people would be more prepared but that doesn't disqualify the investigation any more than this hearing does. >> i want you to respond to that. >> the allegations are vague enough. there's no other location to go. to you can't dust for prints.
