ASHINGTON, May 2 — David Brock, the former right-wing journalist turned liberal, describes himself as once having been a rather large cog in the machinery of the conservative media.
With more than $2 million in donations from wealthy liberals, Mr. Brock will start a new Internet site this week that he says will monitor the conservative media and correct erroneous assertions in real time.
The site, called Media Matters, was devised as part of a larger media apparatus being built by liberals to combat what they say is the overwhelming influence of conservative commentators like Rush Limbaugh and Bill O'Reilly.
Mr. Brock has also said that he knowingly lied in an article he wrote for The American Spectator in 1992 that raised doubts about the credibility of Ms. Hill. The article formed the basis for a later book about Ms. Hill, whose charges of harassment almost derailed Clarence Thomas's appointment to the Supreme Court.
