An anti-war protester who hit Michigan Sen. Carl Levin in the face with an apple pie has been charged with assault.

An indictment filed Thursday charges Ahlam Mohsen of Coldwater with two counts of assault against the Democrat while he was meeting with constituents in August in Big Rapids. Her friend Max Kantar of Big Rapids was also charged.

U.S. Attorney Don Davis in Grand Rapids says elected leaders should be able to listen to constituents without being attacked.

Messages seeking comment were left for Mohsen and Kantar, who are both 23. Mohsen's father, Mohamed Mohsen, said she's unaware of the indictment.

Levin spokeswoman Tara Andringa said he wasn't immediately available for comment. At the time of the incident, the senator said his critics were hurting their cause.
