President Donald Trump’s administration on Monday told a federal judge it lacks authority to bring a man wrongfully deported to El Salvador back to the U.S. because he is in foreign custody, despite a court order directing the administration to “facilitate” the man’s return.

The Trump administration insisted on Sunday that it is not required to work with officials in El Salvador to secure the return of a man mistakenly deported to the country, days after the Supreme Court endorsed a federal judge’s directive that US officials must “facilitate” bringing him back stateside.
