Senate Minority Leader Mitch McConnell joined with former President Trump in endorsing Herschel Walker for Senate. So far, Walker has attracted big name endorsements from GOP lawmakers, a move signaling the GOP is prepared to help Walker flip Georgia from blue back to red in next year’s election.

Walker has been a longtime Trump ally after playing for a team previously owned by the former president.

Fox News reports:

The senator’s endorsement, which was shared first with Fox News and Politico, signals that the GOP Senate leadership – and with it much of the party establishment in the nation’s capital — is rallying around Walker’s bid to challenge Democratic incumbent U.S. Sen. Raphael Warnock in a race next year that may determine if the GOP wins back the Senate majority in the 2022 midterms.

“I am happy to endorse Herschel Walker for U.S. Senate in Georgia,” McConnell said in a statement .”Herschel is the only one who can unite the party, defeat Senator Warnock, and help us take back the Senate. I look forward to working with Herschel in Washington to get the job done.”

Walker thanked McConnell for the endorsement and for “his commitment to bringing the party together toward the collective goal of defeating Senator Warnock. The Democrats have already said they will spend whatever it takes to keep Georgia blue. The stakes have never been higher — if we all work together, we will win next November, and take back the Senate.”

McConnell’s decision to endorse Walker comes after a yearlong feud between the Republican Senator and former President. Trump has repeatedly launched attacks at McConnell, pushing him to leave the Senate and pointing blame to him for losing Georgia to Democrats in last year’s elections.
