A US judge on Monday ordered billionaire Elon Musk’s Department of Government Efficiency to release its internal documents, saying the agency’s work to slash the size of government has been marked by “unusual secrecy.” Since his return to the White House in January, US President Donald Trump has launched a vast offensive aimed at cutting public spending and reducing the role of the federal government. To that end, he tapped Musk, a top campaign donor turned senior adviser, to lead DOGE, which has cut thousands of government jobs and upended agencies — prompting numerous lawsuits.
