Trump this week agreed an "unprecedented, extraordinary migratory agreement" with El Salvador's President Nayib Bukele to send criminals of all nationalities to the country's notorious mega prisons

President Bukele, who labels himself as the "coolest dictator" and a "philosopher king," has built election success and immense popularity on an extreme security policy to combat gang violence in El Salvador, incarcerating large quantities of alleged gang members and securing a massive drop in homicides.

The Trump administration and the president of El Salvador said they struck a deal allowing the U.S. to ship detained migrants and imprisoned criminals to a mega-prison there

Unlike other Latin American leaders, El Salvador’s president is more than embracing US plans to move millions of undocumented migrants off its soil

The lockup currently houses thousands of members of gangs that terrorized the Central American country for decades.

President Nayib Bukele has offered to jail deported criminals from the United States. His prisons have earned him a reputation as being tough on crime, but have raised alarms over rights abuses.
