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.

Caracas launched an investigation into President Nayib Bukele and two Salvadoran officials over alleged human rights abuses against migrants.
