CHARLOTTESVILLE, Va. (AP) — Former Ku Klux Klan leader David Duke has asked a judge to block a subpoena in a federal lawsuit filed by 11 people injured during a violent clash between white nationalists and counterprotesters in Charlottesville last year.

The plaintiffs are seeking to compel Duke to turn over records related to communications he and other white nationalists had before the rally, along with records of efforts to solicit donations.

In court documents, Duke says the subpoena is overly broad and would impose “an undue burden and a significant expense” on him.

A woman was killed when a car drove into a crowd protesting the white nationalists.

Duke initially filed his request in Virginia, where the lawsuit is filed. A judge ruled it should have been filed in Louisiana, where Duke lives.
