ABC News spoke with three Venezuelan men who were released from the notorious CECOT prison in El Salvador.

The Trump administration invoked the Alien Enemies Act — an 18th century wartime authority used to remove noncitizens with little-to-no due process — to deport alleged gang members by arguing that the Venezuelan gang Tren de Aragua is a “hybrid criminal state” that is invading the United States.

The Venezuelans allege that they were beaten and denied access to lawyers while detained at CECOT. They deny being members of Tren de Aragua.
