Alabama Senator Doug Jones will reportedly seek reelection in 2020.

Zach Cohen with National Journal reported Jones, a Democrat, said he’s “already off and running” in the race to keep the seat he won in December 2017 in an upset over Republican Roy Moore. Jones’ win came after Moore, the former Supreme Court Chief Justice in the state, was accused of having improper contact with teenage girls in the 1970s while he was in his 30s.

Moore has denied the claims.

No Republicans have officially announced intentions to challenge Jones, though Rep. Bradley Byrne, R-Fairhope, said he is gauging support from voters before deciding on his 2020 plans.

A Byrne spokesperson confirmed to AL.com the Congressman was “actively considering” a run for the Senate seat.

Another potential candidate is Jeff Sessions, who vacated the Senate seat when appointed U.S. Attorney General by President Donald Trump. Sessions resigned under pressure last week and questions have risen if the Alabama Republican would make a bid for his former post. Sources close to Sessions said he is considering challenging Jones in 2020.
