Elected last year on a promise to crack down on migrants, Trump invoked the 1798 Alien Enemies Act in an attempt to swiftly deport accused members of Tren de Aragua, a criminal gang originating from Venezuelan prisons that his administration labels a terrorist group.

In an overnight ruling blocking the Trump administration from deporting a group of Venezuelans, the justices ignored some of their protocols.

The Supreme Court temporarily blocked the Trump administration from deporting a group of Venezuelans detained in Texas, granting them a reprieve from being imminently sent to a notorious prison in El Salvador.
