Tesla and SpaceX CEO Elon Musk was one of the top 50 donors last quarter to a PAC aimed at maintaining Republican control of the House, new federal filings show.

The Federal Election Commission filings released this week show that Musk donated a total of $38,900 to the PAC Protect The House.

Other high-profile donors who gave to the PAC include Microsoft co-founder Paul Allen, who gave $100,000, and Houston Texans owner Bob McNair, who gave $371,500.

Salon first pointed out Musk’s major donation to the group, which raised more than $8 million in the second quarter.

As the CEO of electric car company Tesla, he has spoken out against climate change and reportedly unsuccessfully lobbied President Trump to institute a tax on carbon.

This week, Musk made an unspecified pledge to help families in Flint, Mich., who were affected by contaminated water.

Musk has also been critical of Trump in the past, and stepped down from two White House councils after Trump pulled the U.S. out of the Paris climate agreement.

The billionaire has described himself as a “socialist,” but was widely mocked on social media after tweeting about it last month.
