Claiborne was convicted in 1984 of tax evasion and served 17 months of a two-year prison sentence before his release in 1987. In 1986 the United States House of Representatives impeached him and the United States Senate convicted him and removed him from office. His impeachment proceedings set a controversial new precedent of using a special twelve-member committee to collect and hear evidence, rather than the full Senate. He maintained that the Justice Department had a vendetta against him and improperly obtained the false testimony of brothel owner Joe Conforte, one of Claiborne's former clients.
