Juan Williams blasted his former employer NPR in a series of interviews on Fox News Tuesday after exec Ron Schiller called Tea Partiers "racist."

"This was an act of incredible condescension," Williams -- who was fired from the radio syndicator last October for making incendiary remarks about Muslims -- told Fox Nation. "...They will say things to your face about how there's no liberal orthodoxy at NPR, how they play it straight, but now you see it for what it is. They prostitute themselves for money."

Schiller -- who resigned Tuesday night -- had been caught on camera by a conservative group headed by James O'Keefe saying the Republican party had been "hijacked" by the Tea Party. (O'Keefe said on CNN that he targeted NPR after the organization fired Williams.)
