David Ernest Duke (born July 1, 1950) is an American white supremacist, antisemitic conspiracy theorist, far-right politician, convicted felon, and former Grand Wizard of the Knights of the Ku Klux Klan. From 1989 to 1992, he was a member of the Louisiana House of Representatives for the Republican Party. His politics and writings are largely devoted to promoting conspiracy theories about Jews, such as Holocaust denial and Jewish control of academia, the press, and the financial system. The Anti-Defamation League described Duke in 2013 as promoting white supremacist views and "perhaps America’s most well-known racist and anti-Semite".
