Elon Musk caused alarm among federal employees and drew ire over an email sent on Saturday requesting that employees summarize their work for the week, and warning on social media that a failure to do so would be taken as a resignation.

Trump claimed Monday that any agencies saying not to respond to the email were doing it "in a friendly manner."

Elon Musk is vowing yet again to fire any federal workers who don’t respond to an email asking them to list five things they accomplished last week.
