WASHINGTON -- U.S. Senate Republican Leader Mitch McConnell endorsed Donald Trump for president Wednesday, a remarkable turnaround from the onetime critic who blamed the former president for 鈥渄isgraceful鈥 acts in the Jan. 6, 2021, Capitol attack but now supports his bid to return to the White House.

McConnell, who was the last top GOP leader in Congress to fall in line with Trump, declared his support in a short statement after Super Tuesday wins pushed the GOP front-runner closer to the party nomination.

The two men had not spoken since 2020 when McConnell declared Democrat Joe Biden the winner of that year's presidential election. But more recently, their teams had reopened talks about an endorsement.

鈥淚t is abundantly clear that former president Trump has earned the requisite support of Republican voters to be our nominee for President of the United States,鈥 McConnell said in the statement.

McConnell said, 鈥淚t should come as no surprise that as nominee, he will have my support.鈥

The nod from McConnell, who has criticized Trump as 鈥渕orally responsible鈥 for the 2021 mob siege of the Capitol, lends an imprimatur of institutional legitimacy to the indicted former president's bid to return to the White House.

It comes after McConnell made his own sudden announcement last week he would step down after this term as leader, a position he has held longer than any other senator, and as he tries one more time to win back Republican control of the Senate, with Trump likely at the top of the GOP ticket.

Trump now counts the GOP leaders in Congress, including Speaker Mike Johnson and Senate Republicans vying to replace McConnell as leader, as backing his bid for the White House.

McConnell said he and Trump 鈥渨orked together to accomplish great things for the American people.鈥
