David Duke, the former Klu Klux Klan leader, is running for U.S. Senate in Louisiana. Duke is a well-established white supremacist, Holocaust denier and anti-Semite. He has endorsed Donald Trump for president. In his announcement video, posted Friday morning to Twitter, Duke says he’ll fight for the rights of “European Americans” and that “The New York Times admitted that my platform became the GOP mainstream.” He touts his opposition to affirmative action and immigration, and cites his joy at Trump’s rise to power. “A revolution is coming in the United States of America,” he says. Duke previously served for one term as state representative in Louisiana. He has run unsuccessfully for the U.S. Senate, the House of Representatives and the governor of the state.
