MILWAUKEE, Wis. (WTAQ) - A 21-year-old man accused of attacking Milwaukee's mayor last summer is getting a plea deal. Anthony Peters is expected to plead guilty to first-degree reckless injury as part of the deal.

Peters' attorney, Tony Cotton, announced the deal with prosecutors who are expected to recommend 9 years in prison.  Authorities say Peters was arguing with his daughter's grandmother last summer outside State Fair Park, when Democratic gubernatorial candidate Tom Barrett intervened. Peters allegedly hit Barrett with a metal object, leaving him with head, mouth and hand injuries. Prosecutor Mark Sanders wouldn't comment Monday.
