According to CNBC, McConnell shared news of his support in a statement on Wednesday, following Trump's sweeping victory on Super Tuesday and defeat of his last standing challenger in the race, Nikki Haley.

"It 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," McConnell wrote.

"It should come as no surprise that as nominee, he will have my support."

McConnell went on to say that during Trump's presidency, they "worked together to accomplish great things," the most important being the appointment of several conservative Supreme Court justices.

"I look forward to the opportunity of switching from playing defense against the terrible policies the Biden administration has pursued to a sustained offense geared towards making a real difference in improving the lives of the American people," he added.

McConnell's support comes after he announced last week that he would be stepping down from his position as leader this year after 17 years of holding the position.
