Federal authorities are making new allegations against William A. White of Roanoke, a neo-Nazi activist who continues to be haunted by his online rantings.

In a revised indictment returned late Tuesday in U.S. District Court in Chicago, White is accused of encouraging violence against a juror -- the same charge that led to his arrest last October and the shutdown of a Web site he used to promote his white supremacy movement.

According to details added to the original indictment, White also made veiled threats against federal prosecutors and an FBI agent.

The charges date back to March 1, 2005, shortly after federal Judge Joan Humphrey Lefkow came home to her Chicago house to find her husband and mother shot to death in the basement.

Because of Lefkow's ties to neo-Nazi activist Matthew Hale -- she ruled against him in a civil case; he was later convicted of plotting to have her killed -- there was speculation at the time that the killings were carried out by white supremacists seeking revenge.

White bought into that theory, writing on his Web site that he was looking forward "to seeing who else this new white nationalist group of assassins kills next," the indictment stated.

Another post to overthrow.com listed five people who "may be next on [the] hit list." The indictment does not name those individuals but describes them as three federal prosecutors, a federal agent and an official with the Anti-Defamation League who were all involved with the Hale case.

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 overthrow.com to promote white supremacy and advocate violence.

It also means that White's trial, which was scheduled to begin March 3 in Chicago, will be postponed.

White, the head of the American National Socialist Workers Party, also faces federal charges of making online threats against various people from the group's headquarters in Roanoke.

At a hearing Wednesday in federal court in Chicago, White entered a plea of not guilty to the latest indictment.

His attorneys say the trial should be moved to Roanoke -- not just because White faces additional charges here, but because he can no longer get a fair trial in Chicago. They also want new prosecutors from outside the Northern District of Illinois.

"The new materials allege that federal prosecutors in this office should be assassinated," defense attorney Nishay Sanan said.

"We believe that is reason for the case to be transferred to a sitting judge outside this jurisdiction."

White, who was led to court wearing an orange jail jumpsuit, remained silent during the brief hearing.

Although Judge William Hibbler had already denied a defense motion to move the case to Roanoke, he agreed to let Sanan and co-counsel Chris Shepherd renew their motion in light of the new developments.

Attorneys will be allowed to submit written arguments, and Hibbler scheduled the next pre-trial hearing for April 2. No new trial date was set.

White, 31, is charged with using his Web site to encourage violence against a member of the Chicago jury that convicted Hale of plotting to have Lefkow killed.

Hale was convicted in 2004, not long after Lefkow presided over a trademark infringement case in which he was ordered to stop using the name of his white supremacy group, then known as the World Church of the Creator.

In a post to overthrow.com last September, White listed the name, address and telephone numbers of the jury foreman in Hale's case.

He made no direct threats, and his attorneys have argued that his actions should be protected by the First Amendment.

Prosecutors, however, have said the post must be taken in context with overthrow.com, which they say was directed at an audience prone to both bigotry and violence.

The indictment cites numerous comments by White on the killings of Lefkow's husband and mother, including this one:

"I don't feel bad that Judge Lefkow's family was murdered today," White allegedly wrote on March 1, 2005. "In fact, when I heard the story I laughed. 'Good for them!' was my first thought."
