CoreCivic (formerly the Corrections Corporation of America (CCA)) is a company that owns and manages private prisons and detention centers and operates others on a concession basis. Co-founded by Thomas W. Beasley, a leader in the Republican Party, Doctor Robert Crants, and T. Don Hutto in 1983, it received initial investments from Hospital Corporation of Americas founder Jack C. Massey, the Tennessee Valley Authority, and Vanderbilt University. As of 2015, the company is the largest private corrections company in the United States. It manages more than 65 correctional and detention facilities with a capacity of more than 90,000 beds in 19 states and the District of Columbia. The company’s revenue in 2012 exceeded $1.7 billion. Controversies related to the company include: treatment of inmates and disclosure of oversight, lobbying efforts to conceal details of operations, a lawsuit about gang influence in Idaho prison and substantial falsification of records, co-operation with local law enforcement in a school drug sweep, and the deadly 2012 riot in a Mississippi facility.
