The Supreme Court early Saturday morning paused the deportation of immigrants potentially subject to the Alien Enemies Act, freezing action in a fast-developing case involving a group of immigrants in Texas who say the Trump administration was working to remove them.

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.

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.
