One of the stars of the HBO cop drama “The Wire” was arrested Saturday in connection with a political argument that reportedly took place outside an Atlanta hotel.

The New York Post reports that Wendell Pierce was arrested on battery charges after he allegedly hit a woman in the head. The incident reportedly was sparked by a political argument between Pierce, who backs Hillary Clinton, and a Bernie Sanders supporter.

Pierce, who played Det. Bunk Moreland on “The Wire,” is known to be politically outspoken and is an activist in his native New Orleans. As an actor he’s also known for his roles as trombonist Antoine Batiste on “Treme” and Teddy on CBS’s “The Odd Couple.” He played Supreme Court Justice Clarence Thomas in the HBO movie “Confirmation,” released last month.

TMZ.com first reported the story, writing: “Sources at the Loews Hotel in Atlanta tell us the actor struck up a convo with the woman and her boyfriend at around 3:30 AM.  The talk turned political and Wendell — a big Hillary Clinton supporter — got upset when the woman declared her support for Bernie. We’re told Wendell … became enraged, pushed the boyfriend and then went after his girlfriend … grabbing her hair and smacking her in the head.”
