Operation Lost Trust was the name of an FBI investigation into the South Carolina General Assembly from 1989 to 1999. By the end of the investigation, seventeen members of the South Carolina General Assembly were arrested for bribery, extortion, or drug use. Operation Lost Trust is often considered the greatest political scandal in the history of the state of South Carolina. It directly influenced the passing of South Carolina's Ethics Reform Act of 1991, and led to the restructuring of the state government in 1993. In its wake, the once-dominant South Carolina Democratic Party was weakened as a political party, and the Republican Party emerged as a viable political entity in the state.
