The Alien Enemies Act: What to know about a 1798 law that Trump has invoked for deportations

The Supreme Court has allowed the Trump administration to use a 1798 wartime law, the Alien Enemies Act, to deport Venezuelan migrants it accuses of being gang members, ending the temporary halt on deportations ordered by a federal district judge. But the court also ruled that the administration must give Venezuelans it claims are gang members the chance to legally fight any deportation orders. It also did not weigh in on Trump’s invocation of the act. The ruling came after the wartime law was used last month to fly more than 130 men accused of being members of the gang Tren de Aragua to El Salvador, where the U.S. has paid to have the men held in a notorious prison. The Trump administration argues that the gang is an invading force.
