fbi doing this kind of investigation now ahead of the hearing rather than local authorities in the jurisdiction where the assault is alleged to have happened? >> the fbi can cooperate and work with those local authorities. very good question. if they have documents or evidence or if there was any report at the time, it should be made available. the polygraph report, as well as the polygrapher perhaps should be there, the therapist whose notes were done as well as those notes. so there are a variety of source of information. the fbi is the one who began the background check on judge kavanaugh. it has responsibility to complete that investigation. it would investigate this kind of crime that bears on the credibility of a supreme court justice, highest court in the land, lifetime appointment, far-reaching consequences for decades and generations to come. >> senator, bloomberg news
