Deep in Florida’s Everglades national park, surrounded by reptile-infested waters, Donald Trump’s immigration officials are busy building a new detention camp. Trucks carrying dirt and portable generators have streamed onto the deserted airstrip now known as Alligator Alcatraz, some 45 miles from downtown Miami.

The detention immigration facility is located in an idle airstrip in the Everglades that the DeSantis administration recently seized from Miami-Dade County using emergency powers.
