FOX News personality Bill O’Reilly was on "Jimmy Kimmel Live" Monday night promoting his book “Killing Patton” when the conversation turned to embattled NBC news anchor Brian Williams.

Kimmel asked O’Reilly  what he thought of his fellow broadcaster’s predicament.

“He made a mistake. Is it a character flaw? I don’t know,” O’Reilly said. “If it is, he’s going to lose his job. If another one comes out, that he exaggerated a story that he reported, he’s going to lose his job.”

O’Reilly also took those to task who have been charging hard for Williams’ resignation.

“Anybody who is enjoying the destruction of this man — you got to look at yourself. And there’s a lot of people who seem to be real happy his career is going down the drain. That disturbs me,” he said.

O’Reilly recounted a trip he made to Iraq during the war, in which he was riding in a helicopter over Baghdad.

“I went to Iraq after him, but it was hot, and we were in a helicopter,” O’Reilly said. “Nobody shot at us or anything like that.”

Williams has come under intense criticism for embellishing on his Iraq helicopter experience on “Late Night with David Letterman,” making up enemy fire that he now admits never happened. O’Reilly said he could understand why Williams may have gone too far on the talk show.

“When you come on a late night show, you don’t want to be a dweeb. You want to have something interesting to say,” O’Reilly said. “What happens is, a journalist will say ‘I was there’ and then a story, to make it more dramatic and interesting, will emerge. He embellished the story. If it was just one time, he’ll get by.”

But if it’s more than one time, O’Reilly doubts he can survive.
