What to know about ‘Alligator Alcatraz,’ Florida migrant detention center in progress

A social media video from Florida Attorney General James Uthmeier shows an aerial view of the Dade-Collier Training and Transition Airport, the planned site of a new migrant detention facility.

Florida’s attorney general says the facility is on track to open in early July, at a little-used airfield in the Everglades. Environmental activists hope they can repeat history and stop the project.
