Over the weekend, former President Trump slammed Senator Minority Leader Mitch McConnell during a donor event hosted by the RNC. While delivering a speech at Mar-a-Lago, Trump called McConnell a “dumb son of a bitch” and also criticized his former vice president for his behavior after the election and leading up to Jan. 6th.

Politico reports:

The former president spent several minutes tearing into McConnell, saying that he didn’t do enough to defend him during the February impeachment trial. At one point, three people familiar with the remarks said, Trump called the Senate GOP leader a “dumb son of a bitch.”

Trump also went after McConnell’s wife, former Transportation Secretary Elaine Chao, for resigning her cabinet post after the Jan. 6 insurrection.

The latest verbal broadside against McConnell, the most powerful Republican still in elected office, comes as Trump reemerges as a dominant force in GOP politics. The former president has, in recent days, sought to rev up his small-dollar fundraising apparatus, and he is issuing a steady stream of endorsements for the 2022 midterm elections, in addition to battles over state party chairmanships.

Though many of Trump’s 2022 endorsements align with McConnell’s preferences, including backing a number of incumbent GOP senators for reelection, he has occasionally gotten crosswise with the Senate leader. Trump has pledged to oppose GOP Sen. Lisa Murkowski in next year’s Alaska elections after Murkowski voted for his conviction in the Senate trial, though McConnell and his top allies say they will support Murkowski’s reelection.

This isn’t the first time Trump has sparred with McConnell. Since January the two Republican powerhouses have each been critical of the behavior and actions of the other.
