VIDEO: Meghan McCain Unleashes On Callista Gingrich For Being 'A Mistress'

In a somewhat awkward attack, Meghan McCain argued on MSNBC Tuesday that Callista Gingrich is doing damage to her husband's presidential primary campaign because she is "a mistress," has an "icy" personality and has caused controversy in Gingrich's campaign.

"As much as you don't like talking about Calllista Gingrich," McCain told the panel of guests on "Now with Alex Wagner," "I think the fact that she was a third wife and a mistress and is coming off somewhat icy and [her] reputation of being somewhat controversial within their campaign is doing damage. Maybe just to politicos, but I think it's something that people, and especially values voters, will bring into the race."

But those criticisms could equally be applied to McCain's mother, Cindy McCain, who was subjected to intense media scrutiny during Sen. John McCain's 2008 presidential campaign.

Cindy McCain began dating Sen. McCain in 1979, nearly a year before he filed for divorce from his first wife, Carol McCain. During the campaign, her fortune, which comes from a family beer distributorship, and her spending habits caused controversy, notably when her husband paused before remembering how many houses he and his wife owned. And her personal style was often described as cold and glazed over during the campaign.

But the remarks come as little surprise for those who've followed Meghan McCain since she first stepped onto the political stage in 2008. She has never been known to shy away from political controversies, and she has disagreed with her father on issues, most notably with her support of same-sex marriage and the repeal of the military's "don't ask, don't tell" policy.
