A federal judge on Thursday moved to extend by one week a temporary restraining order preventing the Trump administration from carrying out plans that would all but dismantle the U.S. Agency for International Development. The order, which Judge Carl Nichols of the U.S. District Court for the District of Columbia said he would file later Thursday, continues to stall a directive that would put a quarter of its employees on administrative leave while forcing those posted overseas to return to the United States within 30 days. Judge Nichols said he would rule by the end of next week on whether to grant the plaintiffs’ request for a preliminary injunction that would indefinitely block key elements of the high-profile Trump administration effort. The plan was driven in large part by Elon Musk, the billionaire tech entrepreneur tasked with making cuts to the federal budget, to shutter an agency he and Mr. Trump have vilified. The Trump directive would affect about 2,700 direct hires of U.S.A.I.D., including hundreds of Foreign Service officers.
