The Council on American-Islamic Relations filed a discrimination claim with the U.S. Equal Employment Opportunity Commission Wednesday, the precursor to a lawsuit against Illinois State Police, after it rescinded its first appointment of a Muslim cleric as chaplain.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." State police declined to be more specific.
