Environmental groups have sued to stop the center, arguing it will hurt the environmentally sensitive Everglades.

OCHOPEE, Fla. (AP) — The first group of immigrants were scheduled to arrive Wednesday night at a new detention center deep in the Florida Everglades that officials have dubbed “Alligator Alcatraz,” the state’s attorney general said.

The first detainees were expected to arrive at Alligator Alcatraz late Wednesday night, even as the immigration detention facility in the Florida Everglades has already faced some operational issues with security and water intrusion.
