Dozens of House Democrats are demanding President Trump confirm that Elon Musk will leave his role in the administration by May 30.

A group of 77 lawmakers, led by Rep. Greg Casar (D-Texas), sent a letter to Trump on Wednesday, emphasizing the tech billionaire can only serve in his role as a special government employee for 130 days.

“Considering the repeated violations of the law by Musk and your administration, we demand an immediate public statement from your administration making clear that Musk will resign and surrender all decision making authority, as required by law, by May 30th,” they wrote.

“In his short time in government, Elon Musk has done enormous harm to working Americans,” they continued, adding, “While millions of Americans are suffering, Musk is continuing to enrich himself and break ethics laws.”

Musk’s stint in the federal government has been highly controversial. As the informal head of the Department of Government Efficiency (DOGE), he has led an effort to slash trillions of dollars in government spending that has included significant cuts to the federal workforce.
