Tea Party Nation is taking back its endorsement of Senate Minority Leader Mitch McConnell (R-KY) in the Republican primary for McConnell’s Senate seat.

Writing on the group’s website on Wednesday, Tea Party Nation founder Judson Phillips referred to a report by Glenn Beck that described a closed door meeting in which McConnell said supporters of conservative groups FreedomWorks and Senate Conservatives Fund are traitors to the Republican Party. Those groups have criticized a number of top Republican lawmakers (including McConnell himself) over efforts to defund Obamacare.

“While endorsing Mitch McConnell seemed like the right thing to do at the time, Mitch McConnell has proven he is not worthy of conservative support,” Phillips writes in the post, titled “Tea Party Nation withdraws endorsement of Mitch McConnell.”

It is time to defund the GOP until the GOP pushes people like Mitch McConnell out of leadership. And if they do not, there are always alternatives for conservatives. While the odds still favor Mitch McConnell being reelected to another term in the Senate, he will do so without our support. Given his behavior, there is simply no reason for conservatives to support McConnell. Regrettably there are no good choices in Kentucky in this election.

In May, writing on McConnell’s reelection website, Phillips endorsed McConnell over Republican Matt Bevin in the Republican primary.
