Rep. Trey Gowdy will return to the private law firm in South Carolina where he worked in the 1990s and will be a white collar criminal defense attorney.

The South Carolina Republican is retiring from Congress in January after serving five consecutive terms.

The Charleston Post and Courier confirmed Gowdy’s return to Nelson Mullins Riley & Scarborough, the Columbia, South Carolina-based firm that represents private individuals as well as corporate clients and provides lobbying services in the state and in Washington, D.C.

Gowdy’s wheelhouse, though, is the courtroom. He was an assistant U.S. attorney for six years before running for South Carolina’s 7th Circuit Solicitor in 2000.

As a member of Congress, he carved out a reputation as a partisan bulldog chairing the House Select Committee on Events Surrounding the 2012 Terrorist Attack in Benghazi, which eventually discovered Hillary Clinton used a private email to conduct official government business while she was secretary of state.
