The White House is insisting the Trump administration did not violate a court order when it deported more than 200 immigrants to El Salvador over the weekend, even as a federal judge ordered the deportations to be temporarily stopped.

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

The Alien Enemies Act of 1798 gives the president wartime powers to deport undocumented immigrants with little to no due process.
