Salvadoran President Nayib Bukele has proposed a prisoner exchange with Venezuela, offering to repatriate hundreds of Venezuelans who were deported from the United States in exchange for “political prisoners.

A judge ruled Wednesday that the Trump administration must facilitate the return of a 20-year-old migrant, who was deported last month, because his removal violated a class action lawsuit settled last year.

Neiyerver Adrian Leon Rengel faced the same fate as hundreds of other Venezuelans men who have been deported to El Salvador based solely on tattoos the U.S. government claims indicate affiliation with the Tren de Aragua gang, even though experts say that, unlike Central American gangs, TdA does not typically use tattoos to identify its members.
