Think Progress notes that O'Reilly smeared them and Media Matters in his interview with Paul Begala and James Carville. Newshounds notes that O'Reilly smeared them as well...
From Think Progress...
O’REILLY: This is ridiculous. There were legitimate questions. Wallace grills Rumsfeld. I grilled Rumsfeld. And come on.
CARVILLE: First of all, I don’t think that FOX has been fair to Bill Clinton. I like you. I like Chris Wallace. I like Sean Hannity. I don’t think in any way, shape or form that…
O’REILLY: Give me an example of unfairness.
CARVILLE: You know, just like Bill Clinton said, you never asked him — how many times was Rice on that show?
CARVILLE: How many times was Rumsfeld on that show?
O’REILLY: What are you talking about?
CARVILLE: Chris Wallace’s show.
BEGALA: Chris Wallace, this is what the President said…
O’REILLY: Does this come from Media Matters? Is that where this comes from?
BEGALA: They’re a great website. Do you ever read them?
CARVILLE: They’re totally documented.
O’REILLY: Hired guns.
BEGALA: Actually, that didn’t. That came from the Center from American Progress, ThinkProgress.
O’REILLY: These far left web sites you guys take this information off, these are paid to smear people they disagree with. Do your own research.
