German revisionist Germar Rudolf will appear Tuesday in the state court in Mannheim, accused of 'denying the Holocaust' since 1997 via documents and on the Internet. 'Denying the Holocaust' is a crime in Germany, where it carries a maximum sentence of five years. U.S. authorities arrested Rudolf in 2005 when he appeared at an immigration office in Chicago to apply for a green card based on his marriage to a U.S. citizen.
