Meghan McCain appeared on Howard Stern’s SiriusXM radio show to promote her “TakePart Live” talk show on Pivot TV. When Stern asked the 29-year-old what her father thinks of the Tea Party favorite, she quickly replied, “They hate each other.”

She repeated the sentiment before wondering aloud if it had previously been publicly disclosed.

“In a fistfight, I’m pretty sure your dad can kick [Paul’s] ass,” Stern quipped to McCain.

“Yeah,” the Vietnam War veteran’s daughter said, “My father’s 76 years old and he can still throw down.” McCain, born in 1936, is actually 78 years old.

McCain and Paul have had a notoriously prickly relationship that has included a number of public spats. The former GOP presidential candidate famously called Paul, Sen.

But any tensions appeared to have eased, at least temporarily, when McCain said last month that he would indeed support Paul if the Kentucky senator is the Republican nominee. “I’ve seen him grow, and I’ve seen him mature, and I’ve seen him become more centrist,” McCain told The New Yorker.

Paul’s office had no comment on Meghan McCain’s remarks. McCain’s office didn’t immediately respond to ITK’s request for comment.
