SAN SALVADOR, El Salvador (AP) — The crown jewel of El Salvador's aggressive anti-crime strategy — a mega-prison where visitation, recreation and education are not allowed — became the latest tool in U.S. President Donald Trump's crackdown on immigration on Sunday, when hundreds of immigrants facing deportation were transferred there.

The Trump administration transferred hundreds of immigrants to El Salvador even as a federal judge issued an order temporarily barring the deportations under an 18th century wartime declaration targeting Venezuelan gang members,

The administration won’t identify those moved — or say whether the Alien Enemies Act, which briefly sped up some deportations, played any role.
