Last night, Bill O’Reilly said that State Department spokesperson Jen Psaki “looks out of her depth."

His comments prompted deputy spokesperson Marie Harf to respond on Twitter:

At the daily briefing, she then said that O’Reilly used “sexist, personally offensive language that I actually don’t think [he] would ever use about a man.”

O’Reilly laughed, “I would never say that about a man, would I? No, not me! Takin’ on the ladies!”

“The Factor” host invited both Psaki and Harf to discuss the controversy on the show tomorrow. There’s no word yet on whether or not they will accept the invitation.
