From this 12/14 article:

The chairman of a federal civil rights panel clashed yesterday with Prince William Board of County Supervisors Chairman Corey A. Stewart over the recent crackdown on illegal immigrants approved by the board.

Linda Chavez, a conservative commentator who heads a U.S. Commission on Civil Rights panel examining whether the crackdown violates federal antidiscrimination laws, said she believed the supervisors based their action largely on anecdotal evidence of problems caused by illegal immigrants...

As Stewart points out, Chavez is a known apologist for illegal immigration, so - surprise! - whoever nominated her to the committee knew what she was going to say.

I'll outsource the rest of this to most of the comments here.
