Authorities said Clark violated a court order in August 2006 by placing several calls to his father-in-law. He had been charged with multiple counts of failure to comply with the order.
Clark's wife, Monica Rodriguez Gonzalez, filed for a domestic violence protective order in June 2006, claiming that Clark had abused her. The order prohibited Clark from having any contact with her and eight other people, including their child.
Clark was disqualified after reaching the finals of the popular TV show's second season in 2003 for failing to reveal a previous arrest.
He later accused "Idol" judge Paula Abdul of coaching him and initiating an affair. She denied his allegations, and Fox TV cleared Abdul of any wrongdoing.
