Dozens of House Democrats wrote to U.S. President Donald Trump on Wednesday “to make clear that you must remove Elon Musk from his government position by May 30th and to demand that you stop ignoring federal law and ethics rules to empower an unelected billionaire.”

Musk, the richest person on Earth, is leading Trump’s effort to gut the federal bureaucracy as the de facto chief of the so-called Department of Government Efficiency—but the billionaire is not the formal head of DOGE. Instead, Musk is a “special government employee,” which lets him keep his financial disclosure form confidential.

The new letter to Trump, signed by 77 House Democrats, highlights that special government employees can only serve in their positions for 130 days in a year and demands “an immediate public statement from your administration making clear that Musk will resign and surrender all decision-making authority, as required by law.”

“In his short time in government, Elon Musk has done enormous harm to working Americans,” noted the coalition, led by Congressional Progressive Caucus Chair Greg Casar (D-Texas). “Musk’s reckless destruction of government agencies has led to everything from seniors having challenges accessing Social Security to veterans losing access to care.”

The billionaire’s business ties include SpaceX and its subsidiary Starlink, the electric vehicle maker Tesla, and the social media site X, which is aiming to add a digital wallet feature. His companies have received tens of billions of dollars in government funding, including through contracts.

“While millions of Americans are suffering, Musk is continuing to enrich himself and break ethics laws,” the lawmakers wrote. “Musk continues to cut funds from programs that support working people, while his own companies continue to rake in more than $8 million per day in contracts and subsidies from the federal government. Recently, your administration changed the rules of a broadband program to give even more money to one of Musk’s companies. Musk held a car show on the lawn of the White House, where he illegally promoted his company’s vehicles.”

The letter continues: “Musk paid Wisconsin voters to support his preferred candidate in the state supreme court race. Any typical government employee would be held accountable for these actions, but Musk, who donated $277 million to your presidential campaign, has been allowed to keep his position of power in your White House.”

“Once Elon Musk is removed from his post, he may not legally return to the federal government this year without divesting from his companies, including Tesla and SpaceX,” the letter concludes. “For the good of the country, Elon Musk should be removed from his position immediately. Under the law, Mr. Musk cannot remain in his position beyond May 30th.”

Politicoreported last week that “Trump has told his inner circle, including members of his Cabinet, that Elon Musk will be stepping back in the coming weeks from his current role as governing partner.”

The Hillpointed out Thursday that “the Tesla CEO has signaled he plans to wrap up his work in the allotted 130-day period. He told Fox News‘ Bret Baier last month that he expects to have accomplished most of his DOGE work in that time frame.”

Still, the letter’s signatories want to ensure that Musk actually leaves the government. Casar told Axios—which scooped the letter—that “we’re making it very clear that the public pressure is only going to ramp up on Republicans between here and May 30.”

Democrats “have legal tools at our disposal, political tools at our disposal,” he said, as well as the “full force of public pressure.”
