US top court orders Trump to return man deported to El Salvador in 'error'

The US Supreme Court has ordered the Trump administration to facilitate the return of a Maryland man, who was mistakenly deported to El Salvador's notorious mega-jail.

The Trump administration had conceded that Kilmar Abrego Garcia was deported by accident, but appealed against a federal court's order to return him to the US.

On Thursday, in a 9-0 ruling, the Supreme Court declined to block the lower court's order.

The judge's order "requires the Government to 'facilitate' Abrego Garcia's release from custody in El Salvador and to ensure that his case is handled as it would have been had he not been improperly sent", the justices ruled.
