(The Center Square) – Billionaire Elon Musk joined President Donald Trump in the oval office Tuesday as the president signed an executive order requiring federal agencies to work with Musk’s Department of Government Efficiency, known as DOGE. The order will require federal agencies to work with DOGE to significantly reduce their labor force. A White House fact sheet, first reported by Semafor, says the order requires agencies hire “no more than one employee for every four employees” that are fired, with some exceptions, including for public safety and law enforcement. DOGE and Musk have dominated the news cycle since Trump took office by exposing an onslaught of controversial federal spending, most notably as USAID, an agency that has been all but destroyed since Trump took office.
