Federal authorities in Chicago are making new allegations against neo-Nazi activist William A. White.

In a superseding indictment returned late Tuesday in U.S. District Court in Chicago, White faces the same charge of encouraging violence against a juror — but with new details alleging that he also made veiled threats against federal prosecutors and FBI agents.

Those individuals, whose names were omitted from the indictment, "may be next on [the] hit list" following the murders of a Chicago judge’s family members, White wrote on his Web site in March 2005, according to the latest indictment.

The new material also includes an online commentary from White about the murders of Judge Joan Lefkow’s husband and mother — a crime that White wrongly assumed at the time was committed by white supremacists.

"I don’t feel bad that Judge Lefkow’s family was murdered today," White wrote in a March 1, 2005 post. "In fact, when I heard the story I laughed. ‘Good for them’ was my first thought."

The superseding indictment does not add new charges or enhance White’s potential punishment if he were to be convicted. But it gives federal prosecutors more ammunition in their efforts to show that he used his white supremacy Web site to encourage violence.

It also means that White’s trial, scheduled to begin March 3 in Chicago, will be continued.

White, the head of the Roanoke-based American National Socialist Workers Party, also faces federal charges of making online threats here in Roanoke.
