The South Carolina Statehouse corruption investigation was a probe into unlawful interactions between members of the South Carolina General Assembly, the political firm of Richard Quinn, Sr., and major state institutions and corporations from 2013 to 2021. The influence of Quinn's consulting firm was called the Quinndom. By the end of the investigation, four members of the South Carolina General Assembly were indicted on public corruption charges. This investigation is often considered the most significant political scandal in the history of the state of South Carolina since Operation Lost Trust in 1989. [1] [2][3][4] Lost Trust directly influenced the passing of South Carolina's Ethics Reform Act of 1991, and led to the restructuring of the state government in 1993. The investigation raised questions about the effectiveness of that reform in the face of political corruption and dark money influence.[5]
