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

A judge has blocked President Trump from using the wartime Alien Enemies Act. This comes after his administration announced the deportation of hundreds of immigrants, alleging they are members of a Venezuelan gang.

The act is a sweeping wartime authority that allows noncitizens to be deported without being given the opportunity to go before an immigration or federal court judge.
