In exchange for jailing more than 200 deportees, El Salvador’s president, Nayib Bukele, has become a favorite of the Trump administration.

The US government said Wednesday it has located a man wrongly deported to El Salvador and whose whereabouts were previously unknown, adding that he is being held in the country’s CECOT maximum-security prison.

The government of El Salvador acknowledged to United Nations investigators that the Trump administration maintains control of the men who were deported from the U.S. to a Salvadoran prison, contradicting public statements by officials in both countries.
