Jeff Sessions, former longtime U.S. senator and U.S. attorney general, might be running for his old senate seat, and reports say the president is clear that he will not support Sessions.

Claire Austin, a Montgomery lobbyist who was communications director for Sessions when he was Alabama’s attorney general and was deputy campaign director on his first Senate campaign in 1996, said Wednesday she’s expecting her former boss to end months of speculation and qualify for the March 3 Republican primary. Friday is the deadline to enter the race.

A New York Times report said if Sessions did enter, he may be verbally attacked by President Donald Trump.

“Mr. Trump sent word to Mr. Sessions through allies that he would publicly attack him if he ran. And (Mitch) McConnell recently approached Mr. Trump, asking him whether his feelings about Mr. Sessions might have improved. The president said he was very much still opposed to Mr. Sessions and would make that clear if he had to, according to a person briefed on the discussions,” the report said.

If he enters the race, the Times said, Sessions risks reigniting the name-calling Trump engaged in during his 21-month stint in Washington D.C. as attorney general. Sessions most notably angered the president over Sessions’ decision to recuse himself from the Russia investigation.

Trump was reported to have called Sessions an “idiot” and a “dumb Southerner” over the decision, and Sessions ultimately resigned at Trump’s request last year. The public spat will make it difficult for Sessions to be the most Trump-like candidate in a deep red state.

Sessions held the U.S. Senate seat from 1997 until 2017, when he left it to accept President Donald Trump’s appointment as attorney general.
