A Venezuelan migrant who was deported to El Salvador's CECOT mega-prison has filed an administrative claim over what he says was his wrongful removal from the U.S.

In March, the Trump administration sent roughly 250 Venezuelan men deported from the U.S. to CECOT amid accusations that they were members of the Tren de Aragua gang, which has been rejected by many of the men as well as their families and attorneys. A prisoner swap recently saw most of the Venezuelans being held at CECOT freed.
