According to a report by the US political news website (Politico) on February 22 local time, Musk, the head of the US government's Department of Efficiency, said on the same day that all US federal government employees must explain the content of their work in the past week or face dismissal. Musk said on social media that in accordance with the instructions of US President Trump, employees will soon receive an email asking federal government employees to explain their work in the past week, and employees who fail to reply to this email will be considered to resign. According to the report, it is unclear which legal authority Musk relies on to make the above remarks. But Trump earlier in the day expressed his appreciation for Musk's work in reducing the size of the US federal government on social media and urged him to "be more proactive".
