Vice President JD Vance unleashed a wave of MAGA-fueled criticism against Sen. Mitch McConnell on Tuesday, delivering a rare public rebuke of the former Republican leader for refusing to back a key Pentagon nominee.

The war of words began shortly after McConnell became the only Republican to vote against Elbridge Colby, who was chosen by President Donald Trump as the Defense Department’s top policy strategist.

“Make no mistake: America will not be made great again by those who are content to manage our decline,” McConnell said in a statement that was quickly circulated on social media.

“Mitch’s vote today—like so much of the last few years of his career—is one of the great acts of political pettiness I’ve ever seen,” Vance noted in an X post.

A wave of other conservative voices joined the VP, fed up with McConnell’s feud with and behavior toward the president.
