Issa previously represented California 49th District in the House, but announced last year that he would not seek reelection. Democratic Rep. Mike Levin won the election to replace Issa in November.

Issa has suggested in recent weeks, however, that he could run for Congress once again if his nomination to a top trade post in the Trump administration was not approved soon.

Issa’s confirmation largely stalled in the Senate last week after Sen. Bob Menendez Robert (Bob) MenendezWatchdog confirms State Dept. canceled award for journalist who criticized Trump Kasie Hunt to host lead-in show for MSNBC's 'Morning Joe' Senators ask for removal of tariffs on EU food, wine, spirits: report MORE (N.J.), the top Democrat on the Foreign Relations Committee, raised concerns about his FBI background file.

Hunter currently represents the nearby 50th District.

His political career has been thrown into turmoil by a federal indictment on charges including campaign finance violations and wire fraud. His wife pleaded guilty to similar charges earlier this year, though Hunter has maintained his innocence. His trial is scheduled for January.

Still, the charges have made Hunter politically vulnerable, even in his deeply conservative Southern California district. In last year’s midterm elections, he eked out a narrow 3-point win over Democrat Ammar Campa-Najjar.

Campa-Najjar is once again running for Hunter’s seat.
