Tio Hardiman has been the leader of Cease Fire Illinois. He was arrested last month and charged with beating his wife.
In the late 1990's he pleaded guilty to domestic battery involving his former wife.
But according to a Sun Times report, Hardiman denied on a job application to the University of Illinois at Chicago in 1999 that he'd been convicted of a crime.
He denies this latest charge.
Hardiman is on leave from Cease Fire which says it won't renew his contract.
