Officials from the Illinois State Police have revoked the appointment of a prominent Chicago-area cleric to be its first Muslim chaplain. In a statement, state police officials said Sheikh Kifah Mustapha, the associate director of the Mosque Foundation in Bridgeview, could not serve as a volunteer chaplain "due to information revealed during the background investigation."

Six years after the U.S. government barred Tariq Ramadan from entering the U.S., the controversial Muslim scholar will speak in Chicago on Saturday -- one of his first American appearances since U.S. Secretary of State Hillary Clinton promised he would no longer be denied a visa for having alleged ties to terrorism. His opponents warn of danger ahead.
