Thora Birch has joined Adrian Grenier and Mimi Rogers in the political thriller “Public Affairs,” Varietyhas learned exclusively.

“Public Affairs” follows a young campaign aide who sleeps with a presidential candidate’s wife — a mistake that sends him into a downward spiral of corruption and blackmail. He is left fighting not only for his career, but also his life.
