Musk caused alarm among federal employees over an email sent on Saturday requesting that employees summarize their work.

"Consistent with President @realDonaldTrump’s instructions, all federal employees will shortly receive an email requesting to understand what they got done last week," said the post. "Failure to respond will be taken as a resignation.

Musk initially said the request was a 'very basic pulse check,' but now says it will root out 'non-existent people or...dead people' who are collecting paychecks.
