(CNN) - Conservative blogger Andrew Breitbart has hundreds of contributors to his website, and one of them is a Republican challenging Illinois Democratic Rep. Jan Schakowsky for her seat in Congress.
On Thursday, in the wake of the Shirley Sherrod firing controversy, Schakowsky called on her opponent, Joel Pollak, to "denounce Breitbart's intentional distortion of the truth and to end any further association with his website, BigGovernment.com."
Backlash against Breitbart has mounted since Monday, when he published a video of Sherrod, a USDA employee at the time, speaking to a crowd of NAACP members in Georgia. Liberals accuse Breitbart of deliberately editing the video to paint a portrait of a racist woman and NAACP members who applaud discrimination.
"Breitbart's publication of a video, which intended to turn the point of her speech into its exact opposite is the lowest form of political mudslinging," Schakowsky said in a statement.
Pollak has used BigGovernment largely as a megaphone to criticize Schakowsky. He has penned 16 blog posts this year, nine of which have mentioned the six-term congresswoman.
Pollak is not paid by Breitbart for his contributions and has no plans to disassociate himself with BigGovernment, his communications director, Shalom Klein, told CNN. But Pollak acknowledges what he sees as errors on all sides.
"Andrew [Breitbart] used intemperate language in his debate with the NAACP, which was wrong," Pollak said in a statement. "It was even more wrong for the White House and the NAACP to punish a woman for alleged racism without conducting a full and fair investigation."
