Elon Musk's days at the White House are over.

White House officials told NBC News that Musk is the CEO of billionaire Tesla President Donald Trump solicited cuts to federal waste.

Two sources later confirmed to NBC News that Musk served more than 114 days in his special government employees who officially ended Wednesday night.

Musk posted a comment on his social media platform X on Wednesday. He called for the “Governor’s Mission” to become “a way of life for the entire government”, referring to his government efficiency initiative.

"As my scheduled time as a special government employee ends, I want to thank President @realdonaldtrump for the opportunity to reduce wasteful spending," wrote Musk, the wealthiest man in the world.

Although senior White House officials had previously stressed that Musk was a friend of Trump, the White House did not provide record comments on Musk's departure on Wednesday.

Special government employees of a class of temporary workers, including Musk, can usually work up to 130 days in a calendar year, although dates can be allocated, NBC News reported. The White House first publicly acknowledged Musk's role on February 3, so he is likely to end at the end of that term.

Musk's official departure is an allegation in his relationship with Trump. On Tuesday, CBS News' "Sunday Morning" shared his disappointment in the "Mass Spending Act" that he said "destroyed" his church business work that aims to reduce federal spending by cutting the size of the federal workforce, reducing government plans and eliminating waste of pattern.

The Congressional Budget Office estimates that the Republican funding program will increase the $2.3 trillion deficit over a decade, largely because Trump's 2017 tax cuts and new spending extensions exceeded savings.

Musk initially planned to cut $2 trillion in the entire operation, but later he stepped back.

Now, he left the administration, and so far the trillions of dollars in savings he had touted on the campaign trails fell far. As of Wednesday night, the Doge government website announced savings of $175 billion, although its claims have been found to be questionable.

Trump responded to Musk's criticism at the Oval Office on Wednesday afternoon and defended the funding plan. He said the legislation would give him several key priorities, but he also pointed out the complexity of passing such a huge bill through such a split house.

"My reaction is a lot of things. First place, we have to get a lot of votes. We can't cut it - you know - we need to get a lot of support, we have a lot of support. We have to get it through the house."

Musk was one of the most obvious people in the early stages of the second Trump administration, gaining Trump's favor while promoting his 2024 presidential campaign, according to the campaign financial report.

He often meets Trump side by side, often wearing a Trump hat when he appears with a little kid. Musk seemed to love his role as Trump’s wasteful and fraudulent Tsar, making his debut at the conservative political action conference in February, a huge chain that promoted his cost-cutting initiative.

Musk also once threatened to use his wealth to fund challengers for any Republican who dared to oppose Trump's agenda.

But behind the scenes, tensions between Musk and other members of the Trump administration have intensified, some of whom reported news reports about tense meetings and shouting games. Musk also made some of his dissatisfactions, including criticism of Trump's tariffs.

Meanwhile, Musk’s public image suffered – and the perception of Tesla, his most consumer-centric business, was also seen. Public opinion polls show that he and Doyle are relatively unpopular, with Tesla's vehicles and dealerships being targeted by protests and vandalism. Tesla's stock has fallen 11% so far this year.

Trump continued to support Musk, turning the White House South Lawn into an impromptu Tesla showroom at one point in March and buying one of the vehicles.

Musk's power was sensational in his cash contribution and political influence when Republicans lost a high-profile judicial election in Wisconsin, where Musk spent a huge effort and became the target of Democrats.

Musk insists that his involvement in the Trump administration is temporary, but in recent weeks he has shown that he may withdraw from politics more broadly. He wrote on X last weekend that he "returned to work hours on 24/7 and went to bed in a conference/server/factory room". Last week, he said he planned to reduce his politically significant spending, although he said he would spend in the future if he saw reasons for doing so. "I have no reason at the moment," he said.

Although Musk has said that Dooger will continue to operate, it is not clear how much pull will be without his helm.

The legacy of Musk-led efforts is likely to be reflected in legislation, as the House is expected to propose a set of revocation plans to codify the Doge cuts.

"We want to make sure Congress passes its first revocation bill, including Doge, and we will send more," Russ Vounding, the office of the director of management and budget, told Fox Business on Wednesday.
