The U.S. Department of Health and Human Services told employees on Monday that they were required to respond to an email from the Trump administration demanding they summarize their work over the past week, reversing its earlier position.

The administration sent out a second round of emails on Friday evening in a renewed push by billionaire Elon Musk and his Department of Government Efficiency team to assess the performance of government employees.

HHS employees, which includes the FDA and CDC, had previously been told that they did not have to respond to DOGE’s emails and there would be “no impact to your employment with the agency if you choose not to respond.”

In Monday’s email, seen by Reuters, the department told employees to respond to the email by midnight and coordinate with supervisors to develop a response.
