Billionaire Twitter CEO Elon Musk endorsed Republicans for the midterm election cycle on Monday, telling voters to cast ballots for a Republican Congress.

Musk’s announcement comes months after he first announced plans to vote Republican earlier this year.

“To independent-minded voters: Shared power curbs the worst excesses of both parties, therefore I recommend voting for a Republican Congress, given that the Presidency is Democratic,” Musk wrote.

The statement follows through on Musk’s vow to vote Republican in May.

“I have voted overwhelmingly for Democrats, historically – overwhelmingly. Like, I’m not sure, I might never have voted for a Republican, just to be clear. Now this election, I will,” he said at the time.
