Gowdy's new job became official minutes after the new Congress was sworn in. Gowdy was a popular lawmaker while in Washington and led the investigation into Hillary Clinton's Benghazi handling.
Trey Gowdy revealed his post-Congress plans Thursday.
The former Republican South Carolina representative will join Nelson Mullins, the South Carolina-based law and lobbying firm announced.
Gowdy, 54, worked at Nelson Mullins through 1994, when he left the firm to become an assistant federal prosecutor.
Joining Gowdy at Mullins’s white collar defense and government investigations team are his longtime chief of staff, Cindy Crick, and Sheria Clarke, the former staff director for the House Oversight Committee, which Gowdy chaired.
