A group of Venezuelan men urgently filed requests to the US Supreme Court, an appeals court and two federal courts to block their imminent deportation, saying President Donald Trump’s administration appears poised to send them to a notorious prison in El Salvador without the required chance for judicial review.

The Trump administration is preparing to deport a new group of Venezuelan men detained in Texas, said the ACLU in an emergency Friday court filing.

Attorneys with the ACLU have been scrambling to try to stop the administration from deporting men held in a north Texas facility.
