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.”

An immigration detention facility located at an isolated Everglades airfield is just days away from being operational, according to Florida officials.

Immigrant advocates said the move creates a whole new form of detention outside the scope of the federal government.
