The 2022 race is Mr. Brooks’ second attempt to snag a seat in the Senate. The congressman initially ran in the 2017 special election to replace Jeff Sessions, who left the Senate to become Mr. Trump’s first attorney general.
In that contest, Mr. Brooks came in third behind former Alabama Supreme Court Chief Justice Roy Moore and then-GOP Sen. Luther Strange, who had been appointed to the seat in the wake of Mr. Sessions’ departure. Mr. Moore went on to defeat Mr. Strange in the primary run-off, but wound up losing the general election after being damaged by allegations of sexual misconduct.
