He wasn't, I have no idea what that comment was about.
Frist came in just as the allotted time for the hearing ended. Rummy & Co had to be in the House for a 2:30 hearing there. The last questioner offered Frist his time to make a few comments, but Frist declined. Then, after it was already 2:30, Frist took advantage of his position as Majority Leader, and made some completely self-serving, "I hope I make the evening news" statement that added nothing to the hearing.
Rummy had already risen to leave, but had to sit back down and listen to Frist "do his thing". I hate it when Republicans act no better than Democrats..but then, among senators, there's hardly any difference.
