Rex Hugh Banner is a U.S. Treasury officer in Washington, D.C. who was briefly sent to Springfield to uphold Prohibition in Springfield after a young boy got drunk in a live news report, which incited several women to force the city government to declare Prohibition. He replaced Clancy Wiggum as Chief of Police and made a main objective to capturing the "Beer Baron", a rumrunner. Also, despite being more competent than Wiggum, Banner seems to be somewhat corrupt, as he will take some bribes.
