A white supremacist leader has been indicted on federal changes for making threats to five individuals and attempting to intimidate witnesses in a federal housing discrimination lawsuit, the Justice Department announced Thursday.

William White, the self-proclaimed commander of the neo-Nazi group the American National Socialist Workers Party, was charged with five counts of communicating threats in interstate commerce, one count of communicating an extortionate threat in interstate commerce and one count of witness intimidation.

The 31-year-old was also recently indicted in the Northern District of Illinois for soliciting the murder of a former federal juror.

The new indictment alleges that, from late 2006 through mid 2008, White terrorized individuals with whom he disagreed on either racial or personal issues. He is accused of making late-night telephone calls to the victims' homes, writing victims threatening e-mails and posting victims' contact and personal information on neo-Nazi Web sites, sometimes accompanied by language advocating their murder.

He also allegedly sent letters to the homes of individuals involved in a federal housing discrimination lawsuit which included racial epithets and threatened consequences for their participation in the suit.

If found guilty, White faces a maximum of 55 years in prison as well as a potential fine of up to $250,000 for each charge.
