The email came from the US Office of Personnel Management, with the subject line “What did you do last week?” The deadline to reply was 11.59pm local time on Monday, though the message did not say failure to do so would lead to termination.
Earlier, Trump said on his Truth Social platform that Musk was “doing a great job, but I would like to see him get more aggressive”.
“Remember, we have a country to save,” the Republican leader added.
Trump has put the tech entrepreneur in charge of the new Department of Government Efficiency (DOGE), tasking him with slashing public spending and tackling waste and alleged corruption.
In the latest cuts, the US Defence Department is to reduce its civilian workforce by at least 5% starting next week.
Trump’s Administration has already begun firing many other federal workers who are on probationary status.
DOGE is a free-ranging entity run by Musk, though its cost-cutting spree has been met with pushback on several fronts and mixed court rulings.
A judge denied a union bid to temporarily halt the firing of thousands of people.
Musk said he would work with Trump for as long as he “can be helpful”, as the pair dismissed concerns over conflicts of interest due to the tech tycoon’s government contracts.
“Elon is doing a great job,” Trump told a meeting of conservative activists, running through a list of what he said were “some of the flagrant scams” that had been uncovered.
“We love Elon, don’t we? He’s a character,” Trump added. “People said, what official position does he have? I said, ‘Patriot’.”
Musk said this week that DOGE was publicising its actions on its website and that the transparency would hold him accountable.
