Credit - Andrew Harnik—Getty Images Elon Musk has announced that his time as the leader of President Donald Trump's Department of Government Efficiency (DOGE) is reaching its end. "As my scheduled time as a special government employee comes to an end, I would like to thank President [Trump] for the opportunity to reduce wasteful spending," Musksaid on X."The DOGE mission will only strengthen over time as it becomes a way of life throughout the government." Tesla CEO Musk has implemented a slew of far-reaching changes in his bid to eliminate waste within the government. His cuts at federal agencies and the termination of billions of dollars of government contracts—many of which have reportedlysince been revived—prompted much criticism. And Musk has personally taken a hit, too. His Tesla showrooms have been the subject ofarson attacksand people have boycotted both him and his businessesin protest.

In February, Musk's leadership was questionedover an emailsent to various government departments, requesting that employees respond within a certain time frame and summarize their work for the week. The email—which boasted the subject line "What did you do last week?"—was sent from the Office of Personnel Management (OPM) to workers in several government departments. Muskadded via social mediathat "failure to respond will be taken as a resignation." However, there was no mention of resignation in the email sent to employees. The email—and Musk's accompanying social media warning—garnered ire from several unions and prominent voices. Everett Kelley, president of the American Federation of Government Employees (AFGE),referred to the directiveas "cruel and disrespectful," and called Musk an "out-of-touch, privileged, unelected billionaire." Some department heads initially instructed their employees to focus on their own internal performance review process, as opposed to responding to the email. FBI Director Kash Patel told employeesin an emailthat they should "pause any responses." Earlier this week, it was reported that the Pentagonhad ended the initiativewith its civilian employees, who will no longer be required to send an email specifying what they did the previous week. Musk has garnered much controversy during his time leading DOGE, specifically for his massive cuts at the federal level which, alongside actions from the Trump Administration, contributed to mass layoffs, the termination of government contracts, andefforts to close entire agencies. DOGEclaimsto have saved an estimated $175 billion for the federal government, a number which hasbeen brought into questionduring various verification attempts. Musk'sgoal to cut $2 trillion dollarshas resulted in amulti-state lawsuitagainst Musk and DOGE, amid allegations that they violated the Constitution by accessing government data systems, canceling contracts of federal agencies, and terminating federal employees. In February, during an appearance at the Conservative Political Action Conference, Musk displayed his penchant for slashing government spending by waving around a chainsaw on stage. He was gifted the mechanical tool by Argentine President Javier Milei, who made the chainsaw a trademark of his when he campaigned to cut public spending in his native country. At a celebratory rally after Trump's inauguration, Musk's White House career got off to a contentious start when he seemingly offered a straight-arm salute at the Capitol One Arena in Washington, D.C., as he excitedly told the crowd: "My heart goes out to you." The motion immediately garnered controversy, with some people, including historyprofessors who study fascismand U.S.Representatives, expressing concern that the action was similar to a Nazi salute. Some, including the Anti-Defamation League, came to Musk's defense, arguing that hewas seeminglymaking an "awkward gesture in a moment of enthusiasm." Musk addressed the controversy himself,saying: "The radical leftists are really upset that they had to take time out of their busy day praising Hamas to call me a Nazi." Several civil service employees resigned from DOGE, citing their refusal to use their expertise to "dismantle critical public services," according to a joint resignation letter sent to the White House chief of staffSusie Wileson Feb. 25, that was obtained by theAssociated Press.The employees had worked for the United States Digital Service, but said their duties had been integrated into DOGE. Musk directly responded to the AP article,calling it"fake news from Associated Propaganda." "These were Dem political holdovers who refused to return to the office," Musk said of the employees. "They would have been fired had they not resigned."There have also been massresignations from top-ranking government officialssince Trump returned to the White House and set up DOGE. David Lebryk, the highest-ranking Treasury Department career official, retired on Jan. 31 after clashing with Musk's team over access to government payment systems, theWashingtonPostreported. Shortly before announcing that his DOGE role was coming to its scheduled end, Musk criticized Trump's "big, beautiful bill" in a public forum.During an interview with CBS, he agreed that the spending bill—which is now heading to the Senate—undermines the spending cuts brought about by DOGE."I was disappointed to see the massive spending bill, frankly, which increases the budget deficit," Musk said. "I think a bill can be big or it can be beautiful, but I don't know if it can be both, [that's] my personal opinion." It isn't the first time that Musk has openly critiqued movements or people from the White House. He previously called out Peter Navarro—the senior counselor for trade and manufacturing, and the architect of Trump's tariffs—calling him "dumber than a sack of bricks." Contact usatletters@time.com.
