The U.S. Supreme Court early on Saturday paused the Trump administration from deporting Venezuelan men in immigration custody after their lawyers claimed they were at imminent risk of removal 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.

Donald Trump began rounding up Venezuelan migrants accused of belonging to the Tren de Aragua gang before expelling them to a maximum security prison in El Salvador.
