Elon Musk tweeted a picture with the words "DOGE" on X, with the text "Department of Government Efficiency" (D.O.G.E). Mr. Trump had previously said that if he won the election in November he would set up a commission on government effectiveness to be led by Mr. Musk. "If given the opportunity, I look forward to serving America," Mr. Musk said on social media. "No pay, no title, no recognition."
