Kilmar Abrego Garcia was deported to El Salvador in March in what the Trump administration admits was a mistake. His family has sued to get him back.

U.S. District Judge Paula Xinis said the government’s refusal to provide certain information in the case has been “an exercise in utter frustration.”
