A month after saying he had “done enough” political spending — and amid a bitter falling out with President Donald Trump — Elon Musk gave $10 million to help Republicans keep control of Congress.

The contributions came as Musk publicly feuded with Trump and was slamming Republicans for voting for the megabill that he argued would blow up the deficit. Still, the SpaceX CEO donated $5 million each to the Congressional Leadership Fund and the Senate Leadership Fund on June 27, according to both groups’ filings with the Federal Election Commission on Thursday.

The next week, the world’s richest man said he would start his own political party.

Musk, who spent $290 million of his own money to boost Trump and other Republicans last year, led the cost-cutting efforts of the so-called Department of Government Efficiency in the first few months of the Trump administration. When he left that role in May, he also suggested he was done with political giving for the time being: “If I see a reason to do political spending in the future, I will do it. I don’t currently see a reason,” he said at the Qatar Economic Forum.

He then engaged in a harsh public fight with Trump in June amid the push to pass the president’s signature budget bill, breaking with the president and, later, the GOP.

Musk’s donations to CLF and SLF were enough to make him the largest known individual donor to the main House and Senate GOP super PACs so far this year, although they reflect only a fraction of the money both raised. Congressional Leadership Fund brought in $32.7 million in the first half of the year, while Senate Leadership Fund raised $26.4 million.

A spokesperson for the Congressional Leadership Fund said it does not comment on donors. Senate Leadership Fund and Musk did not immediately respond to requests for comment on Thursday.

Musk also poured another $45 million of his own money into his super PAC, America PAC, this spring. That group spent primarily on Wisconsin’s Supreme Court race in April, which Musk was heavily involved in publicly.

Its expenses included $27 million for petition incentives, $12.7 million on campaigning related to the Wisconsin race and three controversial $1 million payments to spokespeople selected for signing Musk’s petition opposing “activist judges.” Musk’s preferred candidate in that Wisconsin race, conservative Brad Schimel, lost by 10 points in what was widely seen as a sign of Musk’s electoral drag on Republicans.

In July, Musk said he would create his own political party, the America Party. But Thursday’s FEC filings, which cover only through the end of June, provide no insight into what that effort might look like.
