Hand lettered on a sheet hanging from a porch that says White Supremacy is Terrorism

A federal judge has sanctioned white nationalists for stalling litigation in a case connected to the deadly attacks in Charlottesville two years ago.

The judge on Friday fined Elliot Kline, Matthew Heimbach, and the white supremacist group Vanguard America for refusing to participate in the discovery process, the Associated Press reports. He called their behavior “unacceptable” and threatened “more drastic sanctions,” if they continue to impede the legal process. Already, their slow-walking has stalled the litigation for “months on-end,” the Judge said.

Virginia residents are suing the white nationalists and Vanguard America for their alleged role in inciting violence during the white nationalist Unite The Right rally in August 2017. One person was killed and dozens more injured when a car plowed through a group of peaceful counter-protesters.

Plaintiffs are seeking a court order forbidding white nationalists and other groups from further civil rights violations.
