The detention facility, dubbed “Alligator Alcatraz” due to its location, was spearheaded by Florida Attorney General James Uthmeier, who said on Monday that the center is part of his aim to “support President Trump and [Homeland Security] Secretary Kristi Noem in their mission to fix our illegal immigration problem once and for all.”

Environmentalists objected to the plan to set up “heavy-duty” tents to house undocumented immigrants in one of the country’s most prized natural areas.

The Department of Homeland Security signed plans to house up to 5,000 people in Florida who are either arrested by state officers or detained by federal immigration authorities.
