President Trump visited Florida on Tuesday to tour what’s been dubbed “Alligator Alcatraz,” a controversial migrant detention center in the Everglades that officials say is poised to start filling its bed in a matter of hours.

The president was joined by Homeland Security Secretary Kristi Noem, Florida Gov. Ron DeSantis and other state emergency management officials as he toured the makeshift facility, which the state put together within days of receiving federal approval last week.

“I thought this was so professional, so well done,” Trump said after touring the center, which features rows of fenced-in bunk beds and a razor-wire perimeter. “It’s really government working together.”

The facility is situated within the Dade-Collier Training and Transition Airport, an isolated, 39-square mile airstrip located within the wetlands of the Big Cypress National Preserve, next to Everglades National Park.
