By Alexandra Ulmer (Reuters) -Without billionaire Elon Musk in the Trump administration, his cost-cutting Department of Government Efficiency project is likely to sputter out, a former DOGE staffer said in an interview after leaving the team.

Katie Miller's reported departure from DOGE to work for Musk had the internet speculating that she had left her husband, too.

President Trump said that Elon Musk "will, always, be with us, helping all the way." Musk's tenure as a "special government employee" is formally ending.

Elon Musk's departure from the Department of Government Efficiency draws praise from Republicans and criticism from Democrats, highlighting political divides.

Elon Musk has left the White House with little fanfare after splitting with Trump on policy and failing to meet his DOGE savings goals.

Rather than set government straight, Elon Musk is leaving Washington with the federal budget all cattywampus. Deficit spending is increasing, not waning, and there is a growing school of thought that his “efficiency” effort could end up costing the government as much as or more than it saved.

The Trump administration honored Elon Musk as the billionaire's tenure at the White House comes to an end. President Donald Trump awarded Musk a "key to the White House" in honor of his last day.
