Setting another precedence for the executive office the Obama administration on Sunday called Fox News "a wing of the Republican Party."
So far this has served only to escalate the pre-established war of words against the channel, even as observers questioned the wisdom of a White House war on a news organization.
"What I think is fair to say about Fox -- and certainly it's the way we view it -- is that it really is more a wing of the Republican Party," said Anita Dunn, White House communications director, on CNN. "They take their talking points, put them on the air; take their opposition research, put them on the air. And that's fine. But let's not pretend they're a news network the way CNN is."
