I beleive O'Reilly said last night that the interview was already done (it will be on tape).
I cannot understand the animosity here towards O'Reilly. The guy may not be 100% with conservatives, but he sure speaks with alot of common sense on most issues. And he has done more on exposing the left bias in the media than anyone. Bozell doesn't have a show every night on tv that attracts millions of viewers. Bill has made the media bias a talking point on many occasions.
Looks like it was pre-recorded: FNC showed a preview a short while ago; in the short clip, O'Reilly is NOT giving him a pass.
