Marco Rubio, Stephen Miller, Kirsti Noem, Joseph Mazzara, Emil Bove, Drew Sargent, and everyone else involved in planning, executing, and obstructing justice around the CECOT imprisonments are responsible for Andry's torture and rape. Each bears a share of the blame. Don't ever let them forget it.

Andry Hernandez, one of the detainees who was also released just over a week ago, told NPR that guards routinely beat prisoners with batons in the hallway — or dragged them to a small, windowless cell known as "La Isla," or "The Island," where the abuse was even more brutal. According to Hernandez, 32, the prisoners would be dragged out of their cells for complaining about their conditions, taking a bath outside designated hours, or even for making too much noise. Hernandez, who is openly gay, said he was once taken by the guards to "La Isla" after guards noticed him bathing with a bucket outside designated hours. He said that he was beaten by three guards wearing masks. And forced to perform oral sex on one of the guards. After a couple of hours, he was dragged back to his cell. "CECOT was hell on Earth," Hernandez told NPR from Capacho, Venezuela, where he's now back with his family.
