Hundreds of mostly Venezuelan alleged gang members were deported from the United States to a prison in El Salvador on Sunday, with the Trump administration invoking wartime powers to speed up removals despite a court ruling halting the move.

President Trump commented on video from Salvadorean President Nayib Bukele, showing hundreds of alleged criminal migrants arriving in Central America after being deported from the U.S.

The crown jewel of El Salvador’s aggressive anti-crime strategy is a mega-prison where visitation, recreation and education are not allowed.
