Deep in the hazardous and ecologically fragile Everglades, hundreds of migrants are confined in cages in a makeshift tent detention facility Florida’s Republican governor calls “safe and secure” and Democratic lawmakers call “inhumane.

For the first time since detainees began arriving at Florida’s makeshift immigrant detention center in the Everglades this month, the DeSantis administration on Saturday gave the outside world a brief glimpse inside Alligator Alcatraz, offering limited, guided tours to members of Congress and the Florida Legislature.

The state-arranged tour came after some Democrats were blocked earlier from viewing the 3,000-bed detention center.
