A federal judge has barred the administration of President Donald Trump from deportations under an 18th century law that Trump invoked just hours earlier asserting the United States was being invaded by a Venezuelan gang and that he had new powers to remove its members from the country.

President Donald Trump on Saturday invoked the Alien Enemies Act for the first time since World War II, granting himself sweeping powers under a centuries-old law to deport people associated with a Venezuelan gang.

Trump invoked the Alien Enemies Act against Tren de Aragua members. A federal judge later ordered the administration to turn around any planes that had already taken off.
