Administration officials said they expect the fight over using the wartime act to ultimately head to the Supreme Court.

A federal judge temporarily blocked the Trump administration’s ability to use a sweeping wartime authority to quickly deport some migrants whom the US has accused of being affiliated with the Venezuelan gang Tren de Aragua.

The Trump administration has deported alleged members of a Venezuelan gang from the U.S. despite a court order forbidding it from doing so, saying in an extraordinary statement that a judge did not have the authority to block its actions.
