Speculation about Jeff Sessions's future abounded Wednesday, following his resignation as the nation's attorney general. Sessions, according to several reports, is considering running for his old Senate seat, now held by Doug Jones (D-Mountain Brook). Former state Attorney General Luther Strange, appointed to the seat temporarily following Sessions's resignation, endorsed the idea in a tweet: "Jeff Sessions for Senate in 2020!" Former state Rep. Paul DeMarco (R-Homewood) says that remains to be seen. "As long as he served in the Senate, and before that as an Alabama attorney general, and before that as a U.S. Attorney, I don't think it would surprise anyone for Jeff Sessions to come back to Alabama and say he is retired from public life," DeMarco said. "But hey, it's Alabama politics, and anything is possible." Congressman Bradley Byrne (R-Fairhope) is considering challenging Jones, who's widely seen as the most vulnerable Senate Democrat up for reelection in 2020.
