The threat, issued in a post on the social media site X, was made just hours after President Donald Trump posted on his own social media network Truth Social that DOGE should get more aggressive in its attempts to downsize and reshape the federal workforce.

Elon Musk, the unofficial leader of DOGE, or the Department of Government Efficiency, on X said failure to respond would be taken as a resignation. OPM on Monday told workers a response is voluntary after the email spurred backlash from federal agencies.
