According to a report by the US Political News website (Politico) on February 22 local time, Musk, head of the U.S. government efficiency department, said on the same day that all U.S. federal government employees must explain their work in the past week, otherwise they will face dismissal. Musk said on social media that employees will receive an email soon following instructions from President Trump, which will ask federal government employees to explain their work over the past week and fail to respond to the email. Employees will be deemed to be resigned. According to the report, it is not clear which legal authority Musk relies on to make the above remarks. But Trump praised Musk's work on social media earlier that day in reducing the size of the U.S. federal government and urged him to "be more proactive."
