Mitt Romney laughed off a question about whether he's worried about Newsweek's latest cover story labeling him a "wimp."

"If I worried about what the media said I wouldn't get much sleep and I'm able to sleep pretty well," he said in an interview that aired Sunday on CBS' "Face The Nation."

Asked if he's ever been called a wimp before, Romney said with a laugh, "I don't recall that, no."
