CHARLOTTESVILLE, Va. (WVIR) - Three out of four people charged in relation to last August's violent events are telling a judge in Charlottesville's federal court that they aren’t guilty of conspiring or intending to cause a riot in the city's streets last year.

Prosecutors have called these men "serial rioters," and say they are all connected to a white nationalist group out of California.

Three California men arrested last month for their alleged roles in last year's white supremacist violence appeared in Charlottesville Federal Court on Thursday, November 1.

Benjamin Daley, Thomas Gillen, and Michael Miselis pleaded not guilty to charges related to rioting on August 11 and August 12 of 2017.

Gillen and Miselis are currently being held at the Albemarle-Charlottesville Regional Jail.

A trial date will be set following the arraignment of the fourth man, Cole White, who has not yet appeared in court.

All of them are believed to be part of the “alt-right” nationalist group called Rise Above Movement (RAM), which places an emphasis on street fighting.

Four more alleged members of RAM are facing federal charges in California.

They're accused of intending to cause a riot in three cities on the West Coast, as well as in Charlottesville.
