Former Attorney General Jeff Sessions is strongly thinking of running for his old U.S. Senate seat in Alabama in 2020, it was reported Monday. "He is seriously considering a campaign," a Republican operative with knowledge of Sessions' plans told CBS News. The 72-year-old former attorney general served as a GOP U.S. Senator from Alabama for 20 years before former prosecutor Doug Jones won a special election in late 2017 to become the first Democrat in 25 years to win a Senate seat in the state. The race drew huge attention due to several allegations of sexual misconduct levied against Jones' Republican opponent, former Judge Roy Moore. Sessions has until Nov. 8 to decide whether or not he wants to run against Jones, who is considered one of the most vulnerable Democratic candidates in the heavily Republican state. The former attorney general will face a crowded field for his old Senate seat, as there are already five GOP candidates running against Jones: Moore, Rep. Bradley Byrne (R-Alabama), State Rep. Arnold Mooney (R-Alabama), Secretary of State John Merrill (R) and former Auburn University football coach Tommy Tuberville. SLIDESHOW: TOP DEMOCRATS RUNNING FOR PRESIDENT IN 2020 Sessions has the most funds to compete in the Republican primary for the Senate seat in Alabama: the former attorney general has $2.5 million in his campaign account. On Jeff Sessions/possible Senate run, @theabstoddard: "He served for decades and he is a committed conservative. Popular in Alabama. Thought he would be Attorney General for a long, long time. This is an incredible soap opera." #AMRstaff — Andrea Mitchell (@mitchellreports) October 29, 2019 Sessions was forced to resign as attorney general the day after the 2018 midterm elections after he and President Donald Trump had an infamously bitter feud over the Alabama Republican's decision to recuse himself from the Department of Justice's investigation into Russian meddling in the 2016 election.
