Bill O’Reilly visited The Late Show with David Letterman last night where he argued that “folks decided” he was not guilty of any of the many fabrications he has been accused of – because his ratings went up. But have they stayed up? Letterman asked O’Reilly if there’s a similarity between his situation and Brian Williams (currently on suspension from NBC News because he was caught exaggerating his Iraq war experiences). “Only if I did something that wasn’t true,” O’Reilly said.
