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.”

Abrego Garcia’s lawyers contend the administration hasn’t shown “the slightest effort” toward retrieving him after his mistaken deportation. And they point to President Donald Trump’s interview last month with ABC News, in which he said he could bring Abrego Garcia back but won’t.
