An indictment handed up Thursday by a federal grand jury also charged Ahlam Mohsen, 23, of Coldwater with assaulting a federal officer, The Grand Rapids Press reported. Max Kantar, 23, who was with Mohsen during the incident Aug. 16 in a Big Rapids, Mich., restaurant, faces the same charges.
Levin, D-Mich., chairman of the Armed Services Committee, was meeting constituents when he was hit with the pie. The indictment says Mohsen and Kantar assaulted a federal officer while he was carrying out official duties.
Mohsen already faces state charges for the alleged assault. She was arrested in 2009 for refusing to leave Levin's office in Lansing.
She has said she opposes U.S. support for Israel and its military policy in the Middle East.
