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.

Lawyers for Venezuelan men detained in Texas asked the U.S. Supreme Court on Friday to block what the lawyers said were the men's imminent deportation by the Trump administration without the judicial review previously mandated by the justices.

As ACLU attempts to remove more Venezuelan detainees, government lawyers say the administration reserves the right to have removal flights Saturday.
