The Trump administration is asking an appeals court to suspend a judge's order for the government to broker the return of a Maryland man who was mistakenly deported from the U.S. to an El Salvador prison.

A U.S. judge ruled on Friday that the Trump administration must return a Maryland man who was wrongly deported to El Salvador to the United States within three days, the latest legal setback for the administration's hardline deportation policies.

Kilmar Abrego Garcia was taken to El Salvador on March 15 because of what the Trump administration has called an "administrative error."
