Donald Trump's campaign disavowed a robocall by Louisiana senate candidate and former Ku Klux Klan grand wizard David Duke, in which he urged people to vote for Trump and himself.

In the robocall, reported by Buzzfeed on Monday, Duke says he'll "tell the truth that no other candidate will dare say."

"Unless massive immigration is stopped now, we’ll be outnumbered and outvoted in our own nation," Duke says in the robocall. "It’s happening. We’re losing our gun rights, our free speech. We’re taxed to death. We’re losing our jobs and businesses to unfair trade. We’re losing our country. Look at the Super Bowl salute to the Black Panther cop killers."

"It’s time to stand up and vote for Donald Trump for president and vote for me David Duke for the U.S. Senate," he says.

Trump's campaign said in a statement to Politico it had "no knowledge" of the robocall.

“Mr. Trump has continued to denounce David Duke and any group or individual associated with a message of hate,” the Trump campaign told Politico. “There is no place for this in the Republican Party or our country. We have no knowledge of these calls or any related activities, but strongly condemn and disavow."
