Isiah Whitlock, Jr. (September 13, 1954 – December 30, 2025) was an American actor. He is most famous for his role on the HBO television series, The Wire as corrupt state senator Clay Davis. In 2011, Whitlock played an insurance agent named Ronald Wilkes in the film Cedar Rapids. Wilkes is a self-described fan of The Wire and does an impersonation of character Omar Little.
