Who else is on the WH propaganda payroll?

This is a question that's been showing up on the blogosphere, as here in a reader's comment to Josh Marshall.

Apparently, it's not a bad question to ask.

Snow was shaking his head at Williams' indiscretion, and Chavez was upset and joked that she had received bupkis from the White House. Prior to going on air, she had complained that ArmstrongGate had caused some people to assume that she and other conservative commentators were also riding this gravy train. Since the story broke on Friday, she said, several people had asked her how much she had received from the Bush administration. She was pissed at Williams for conduct that was raising questions about the whole cadre of rightwing pundits. During our non-debate on Williams, I noted that it was a waste of taxpayer money to pay Williams for supporting the Bush administration, which he seemed quite willing to do for free. And I wondered aloud how this contract had come to be.

After our segment finished, Chavez and I headed to the green room, and there he was: Armstrong Williams. He was waiting to go on air to defend himself.

[...]

And then Williams violated a PR rule: he got off-point. "This happens all the time," he told me. "There are others." Really? I said. Other conservative commentators accept money from the Bush administration? I asked Williams for names. "I'm not going to defend myself that way," he said. The issue right now, he explained, was his own mistake. Well, I said, what if I call you up in a few weeks, after this blows over, and then ask you? No, he said.

Does Williams really know something about other rightwing pundits? Or was he only trying to minimize his own screw-up with a momentary embrace of a trumped-up everybody-does-it defense?

Maybe we should ask Robert Novak.
