Elon Musk is again using tactics that he has employed at his company X and trying to apply it to the federal government.

In an email, Elon Musk told hundreds of thousands of federal workers they have until just before Tuesday to explain what they accomplished over the last week. Some departments told employees not to respond.

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. Several agencies are telling employees to ignore the email for now.
