Operation Tennessee Waltz was a sting operation set up by federal and state law enforcement agents, including the Federal Bureau of Investigation (FBI) and Tennessee Bureau of Investigation (TBI). The operation led to the arrest of seven Tennessee state lawmakers and two men identified as "bagmen" in the indictment on the morning of May 26, 2005, on bribery charges. The FBI and TBI followed these arrests with an additional arrest of two county commissioners, one from Hamilton County, and the other a member of the prominent Hooks family of Memphis. Investigators also arrested a former county administrator.
