Mitt Romney has appeared on Leno’s show in the past, and in the recent revealed video taped during Romney’s speech to a private Florida fundraiser in May, he said CBS's “Late Show” host David Letterman hates him because he’s been on Leno’s show so often.
"I've been on 'Letterman' a couple of times," Romney said in the video. "I've been on 'Leno' more than a couple times, and now Letterman hates me because I've been on 'Leno' more than him. They're very jealous of one another, as you know."
Letterman on Wednesday night’s show said that’s not so.
"I don't hate Mitt," he said. "I think now more than ever he and his lovely wife, Mrs. Mitt, are more than welcome to come on the show. If you think you're going to get to the White House, you've got to spend time in this chair."
