A federal judge in Ohio will decide whether to revoke the bond for one of four men accused of raising money for a former al-Qaida leader.
A hearing on the request by prosecutors is scheduled for Tuesday in Toledo.
Court officials say Sultane Room Salim has twice violated terms of his release, including briefly leaving a Columbus mosque during prayer services while he was out on bond.
U.S. marshals took Salim into custody earlier this month.
Salim was released from prison in November on bond. A judge ordered him to live with his wife and mother in the Cambridge area of eastern Ohio while awaiting trial.
His attorneys have denied his involvement in what prosecutors say was an effort to raise money for former al-Qaida leader Anwar al-Awlaki.
