David BrockDavid Brock (born July 23, 1962) is an American liberal political consultant, author, and commentator who founded the media watchdog group Media Matters for America. He has been described by ''Time'' as "one of the most influential operatives in the Democratic Party" while others believe his tactics led to Hillary Clinton's defeat in the 2016 presidential election.
Brock began his career as a right-wing investigative reporter during the 1990s. He wrote the book ''The Real Anita Hill'' and the Troopergate story, which led to Paula Jones filing a lawsuit against Bill Clinton. In the late-1990s, he switched sides, aligning himself with the Democratic Party and in particular with Bill and Hillary Clinton.
In 2004, he founded Media Matters for America, a non-profit organization which describes itself as a "progressive research and information center dedicated to comprehensively monitoring, analyzing and correcting conservative misinformation in the U.S. media". He has since also founded super PACs called American Bridge 21st Century and Correct the Record, has become a board member of the super PAC Priorities USA Action and has been elected chairman of Citizens for Responsibility and Ethics in Washington (CREW).
