 --

In what some might consider an act of GOP political suicide, Newt Gingrich slammed Fox News earlier this week, saying that the cable news channel has favored Mitt Romney throughout the 2012 Republican race —and that CNN has been the more "fair-and-balanced" network this cycle.

"I think Fox has been for Romney all the way through," Gingrich said during a meeting with tea party leaders in Delaware on Wednesday, according RealClearPolitics.com, which said it was granted access to the private event. "In our experience, Callista and I both believe CNN is less biased than Fox this year. We are more likely to get neutral coverage out of CNN than we are of Fox, and we're more likely to get distortion out of Fox. That's just a fact."

The former House Speaker blasted the Roger Ailes-led network, blaming Rupert Murdoch, chairman and CEO of Fox News-owner News Corp., for the bias.

"I assume it's because Murdoch at some point said, 'I want Romney,' and so 'fair and balanced' became 'Romney,'" Gingrich said. "And there's no question that Fox had a lot to do with stopping my campaign because such a high percentage of our base watches Fox."

"This is nothing other than Newt auditioning for a windfall of a gig at CNN —that's the kind of man he is," a spokeswoman for Fox News responded in a statement to Yahoo News. "Not to mention, he's still bitter about the fact that we terminated his contributor contract." (Gingrich was dropped by Fox last year shortly before he announced his presidential bid.)

Gingrich added that he will attend the White House Correspondents' Association dinner later this month —as a guest of CNN.

"The only press events I go to are interesting dinners when the wife insists on it, so we're going to go to the White House Correspondents' dinner because she wants to. And we're actually going to go to CNN's table, not Fox."
