Over the course of U.S. history, twenty Members of Congress have been expelled by their colleagues. Most of those cases were based on charges of disloyalty to the United States in the early Civil War period. Two of them followed convictions on charges of public corruption, most recently in 2002.
A new report from the Congressional Research Service surveys the history of congressional expulsions and the related case law. See Expulsion of Members of Congress: Legal Authority and Historical Practice by Cynthia Brown and Todd Garvey, January 11, 2018.
