WASHINGTON (AP) — A federal judge has dealt President Donald Trump and billionaire ally Elon Musk their first big setback in their dismantling of the U.S. Agency for International Development, ordering a temporary halt to plans to pull thousands of agency staffers off the job. U.S. District Judge Carl Nichols, a Trump appointee, also agreed to block an order that would have given the thousands of USAID workers the administration wanted to place on abrupt administrative leave just 30 days to move back to the U.S. on government expense. Both moves would have exposed the U.S. workers and their spouses and children to unwarranted risk and expense, the judge said.
