Attorney General Jeff Sessions arrives on Capitol
FILE - Then-Attorney General Jeff Sessions arrives on Capitol Hill in Washington, June 13, 2017, to testify before the Senate Intelligence Committee.

Former Attorney General Jeff Sessions is expected to announce Thursday that he will run for his old Senate seat in Alabama.

Sessions held the Senate seat from 1997 until 2017, when he was named President Donald Trump’s first attorney general.

He was forced out of office last November after repeatedly clashing with Trump.

He was frequently mocked by Trump after he recused himself from special counsel Robert Mueller’s investigation into Russian meddling in the 2016 presidential election.

If he wins the Republican primary set for March 3, he will face Democrat Doug Jones, who won the 2017 special election to fill Sessions’ seat.
