The Trump administration has confirmed to a federal judge that a Maryland man who was mistakenly deported last month remained confined in a notorious prison in El Salvador. But the government’s filing on Saturday ignored the judge’s demands that the administration detail to the court what steps it was taking to return Kilmar Abrego Garcia to the United States and said he is under the authority of the El Salvador government. The filing comes one day after a U.S. government attorney struggled in a hearing to provide U.S. District Judge Paula Xinis with any information about Abrego Garcia’s whereabouts.
