Florida officials argue a lawsuit over the Everglades detention center was filed in the wrong court, as environmental groups seek to halt expansion.

Alligator Alcatraz, the migrant detention center in the Florida Everglades, is surrounded by swamps infested with massive Burmese pythons.

A federal court ruled that California's ban on private prisons and detention centers like San Diego's Otay Mesa Detention Center, owned and operated by private company CoreCivic, and where migrant children were detained separately from their parents, is unconstitutional.
