His mistaken deportation became a flashpoint in tensions over the Trump Administration’s hardline immigration policy.

At the notorious CECOT prison, he was forced to frog-march, had to kneel from 9 p.m. to 6 a.m. and was subjected to beatings and threats, his lawyers said Wednesday.

Kilmar Abrego Garcia says he suffered severe beatings, severe sleep deprivation and psychological torture in the notorious El Salvador prison the Trump administration deported him to in March, according to court documents filed Wednesday.
