Former Alabama Sen. Jeff Sessions is “strongly considering” running for the Senate seat he vacated in 2017 to become President Trump’s attorney general, according to a published report.

Politico, citing “multiple Republican sources,” reported Monday that Sessions is weighing a campaign for his old seat.

If he runs, Alabama’s former junior senator would join a Republican primary field that includes ex-Auburn football coach Tommy Tuberville, Rep. Bradley Byrne, R-Fairhope, Alabama Secretary of State John Merrill, Alabama state Rep. Arnold Mooney, R-Indian Springs and northwest Alabama businessman Stanley Adair. The winner of the primary would challenge Democratic Sen. Doug Jones in November 2020.

A potential Sessions entry into the race would put the former senator near the top of the money race. He has nearly $2.5 million cash on hand in his campaign account, according to Federal Election Commission records. Byrne leads the race in fundraising with $2.5 million.

Sessions, 72, left an extremely safe Senate seat to join the Trump administration as attorney general. He was the first sitting senator to endorse Trump in the 2016 presidential primary, but Trump’s and Sessions’ relationship deteriorated after the attorney general recused himself from the Russia investigation.

Trump began to belittle Sessions in public, particularly on social media, calling his attorney general “weak” and accusing him of being disloyal.

In private, Trump reportedly called Sessions a “dumb Southerner” and “mentally retarded” according to journalist Bob Woodward’s book “Fear.”

Trump denied the allegations.

The already discredited Woodward book, so many lies and phony sources, has me calling Jeff Sessions “mentally retarded” and “a dumb southerner.” I said NEITHER, never used those terms on anyone, including Jeff, and being a southerner is a GREAT thing. He made this up to divide! — Donald J. Trump (@realDonaldTrump) September 5, 2018

Meanwhile, Sessions said he is still supporting Trump as the president gears up for his re-election campaign.

During an appearance at a Republican fundraiser in Huntsville earlier this month, Sessions said Trump has upheld his promises to the American people.

“That’s why I still do support him," Sessions said.
