A professor whose views on the Holocaust irked critics plans to risk arrest by showing up on the first day of classes next week at DePaul University after officials canceled his courses, took away his office and put him on leave.

The private Chicago Catholic university recently informed professor Norman Finkelstein that his three courses were canceled after a dispute over tenure that drew charges of anti-Semitism against him.

Critics find issue with Finkelstein, the son of Holocaust survivors, who believes that some Jews have exploited the Holocaust. Finkelstein is the author of five books, including "The Holocaust Industry: Reflections on the Exploitation of Jewish Suffering."
