The petition expands those covered by the ACLU's request to all migrants held at the CECOT megaprison, not just those at risk of being sent there.

Lawyers for a group of at least 137 Venezuelan men sent to a prison in El Salvador last month have urged a judge to order Republican President Donald Trump's administration to facilitate their return to the U.

A judge ruled Wednesday that the Trump administration must facilitate the return of a 20-year-old migrant, who was deported last month, because his removal violated a class action lawsuit settled last year.
