A migrant from Venezuela deported by the Trump administration to El Salvador has taken the first step toward suing the U.S. government, saying he was wrongly sent to a notorious prison in the Central American country where he was beaten by guards and kept from contacting his family or an attorney.

A Venezuelan migrant who was deported from the U.S. to El Salvador's CECOT mega-prison in March filed an administrative claim Thursday over what he says was his wrongful removal from the U.S. without due process.

The more than 200 Venezuelan migrants who were deported by the Trump administration to El Salvador's mega-prison in March have left El Salvador to be sent to Venezuela as part of a prisoner swap that included Americans being held in Venezuela, El Salvador President Nayib Bukele announced on X.
