White Supremacist David Duke Announces US Senate Run With Praise for Donald Trump Former Ku Klux Klan leader David Duke is running for U.S. Senate.

 -- White supremacist and former Ku Klux Klan leader David Duke announced a run for U.S. Senate in Louisiana in a web video today, linking his campaign to the message of Donald Trump’s presidential bid.

“I was the first major candidate in modern times to promote the term and policy of ‘America First,’” Duke said. “We cannot have free trade without fair trade.”

“I’m overjoyed to see Donald Trump and most Americans embrace most of the issues I’ve championed for years,” he said. ”I’ve always opposed these wars that lead our nation to disaster.”

Duke endorsed Trump's presidential run in February, and called on supporters to help the New York developer's White House campaign.

Trump was criticized by Democrats and Republicans for not doing enough to distance himself from the former KKK leader's support, as well as re-tweeting white supremacist imagery.

Duke, a former Louisiana state legislator, is entering a crowded field that includes Rep. John Fleming, R-Louisiana, a businessman-turned-member of Congress with tea party credentials, Rep. Charles Boustany, R-Louisiana, and state treasurer John Kennedy. They are running for the seat currently held by David Vitter, a Republican, who has announced that he will not be seeking re-election.

Duke has unsuccessfully sought a Senate seat before. He also ran for president unsuccessfully in 1992.

Under Louisiana’s "jungle" primary system, if no candidate wins a majority of votes in November, the top two candidates will face off in a December runoff election.

The National Republican Senate Committee Executive Director Ward Baker was quick to say the committee would not be supporting Duke.

Duke's leading opponents have also denounced his rhetoric and Senate campaign.
