Derek Black, who won an election for the party post after campaigning around West Palm Beach, Fla., says Palm Beach County GOP Chairman Sid Dinerstein is trying to block his rightful spot on the committee because he did not sign a party loyalty oath, the Palm Beach (Fla.) Post reported Monday.

Black is the son of Don Black, a former Grand Wizard of the Knights of the Ku Klux Klan, and is supported by another former KKK grand wizard, former Louisiana legislator David Duke.

"We're going to fight," Duke said. "I know Derek Black is going to fight for his constitutional liberties. That's why I'm here, because I want to assist Derek." When asked if he thought voters knew who they were voting for when they cast ballots for Black, Duke said, "Irrelevant question. He got the votes. He won election."

"(Black) participates in white supremacist activities," Dinerstein told the Post. "We're the party of Lincoln. We're the party that says we don't judge anybody by the color of their skin."
