U.S. Rep. Mo Brooks, who helped lead GOP objections to President Donald Trump's loss and came under fire for remarks he made preceding the attack on the U.S. Capitol, on Wednesday stressed his support for Trump as he began his Senate bid. But Brooks declined to commit to supporting Sen. Mitch McConnell for GOP Senate leader. The north Alabama firebrand is seeking the seat that will be vacated when Sen. Richard Shelby retires.
