GOP Rep. Mo Brooks on Monday announced his run for the Alabama Senate seat once held by Attorney General Jeff Sessions.

“I am running for the United States Senate because America’s status as the greatest nation in world history is at risk, because Congress is failing the American people by not rising to the challenges America faces, and because I am the only candidate for the Senate who has a record of proven conservative leadership,” Brooks, who represents Alabama’s 5th Congressional District, said in a statement.
