Kilmar Abrego Garcia alleges "severe mistreatment" and "psychological torture" at Salvadoran mega-prison

Kilmar Abrego Garcia — the man whose mistaken deportation by the Trump administration has fueled a monthslong legal saga — alleged Wednesday that he faced "psychological torture" and "severe beatings" after he was sent to a supermax prison in El Salvador earlier this year.

The new allegations emerged in a legal filing by attorneys for Abrego Garcia in Maryland federal court, seeking to amend his lawsuit against the Trump administration over his deportation. Abrego Garcia was flown back to the United States in early June — months after a Maryland judge ordered his return — and promptly charged with human smuggling in Tennessee, but his attorneys say they're concerned he could be deported again.

Abrego Garcia's lawyers have previously described his more than three-week stint at El Salvador's Terrorism Confinement Center, or CECOT, as "torture."
