Joy Behar and Whoopi Goldberg's walkout on The View Thursday is still a hot topic.

She and Goldberg, 54, had been in a heated debate over the mosque near Ground Zero. O'Reilly, 61, set them off when he declared Muslims "killed us on 9/11" (see the video).

"He's an idiot!" Behar, 68, told PopEater after the show. "I just couldn't sit there any longer and listen to him."

On her Headline News show Thursday night, Behar continued her O'Reilly rant, stating that he had a "pinhead moment."

She said she was "really angry ... I thought he was saying something that I construe as hate speech, frankly."

To say Muslims were responsible for 9/11, "to lump an entire group like that," is wrong, she said.

O'Reilly also weighed in on The View incident during his "Talking Points Memo" on Fox News' The O'Reilly Factor Thursday night.

Defending his controversial remarks, he said, "I am not in the business of sugar coating harsh realities ... I enjoy jousting with The View ladies because, with the exception of Elisabeth Hasselbeck, they don't see it my way. I loved that exposition today. Didn't you?"
