FactCheck.org is a nonprofit website that aims to reduce the level of deception and confusion in U.S. politics by providing original research on misinformation and hoaxes. It is a project of the Annenberg Public Policy Center of the Annenberg School for Communication at the University of Pennsylvania, and is funded primarily by the Annenberg Foundation. Kathleen Hall Jamieson's 1993 book Dirty Politics, in which she criticized the presidential campaigns of George H. W. Bush and Michael Dukakis in 1988, provided the idea for FactCheck.org.
