The first group of illegal immigrants arrived in Florida’s migrant detention center, dubbed “Alligator Alcatraz,” on Wednesday night, just one day after President Donald Trump toured the facility.

The illegal immigration detention facility was built far ahead of schedule, just weeks after being proposed by Florida Attorney General James Uthmeier. The facility is in a remote location in the Florida Everglades, with dangerous wildlife providing natural containment. Its first residents arrived in a motorcade of three white Ford vans.
