Former Wire and Treme star Wendell Pierce was arrested early Saturday morning in Atlanta after allegedly becoming violent during a 3:30 a.m. argument about Bernie Sanders with a woman and her boyfriend, TMZ reports. Pierce, who played Clarence Thomas in the recent HBO film Confirmation, is a politically active New Orleans native who supports Hillary Clinton in the Democratic primary. From TMZ, which says the incident took place at the Loews Hotel:

We’re told Wendell … became enraged, pushed the boyfriend and then went after his girlfriend … grabbing her hair and smacking her in the head.

Our source says the girl and her boyfriend went to their room and called hotel security, who then called cops. Pierce was arrested and booked for battery.

Pierce posted bond and was released from jail. He doesn’t appear to have yet commented on the allegations.
