A state-run detention facility for migrants has opened in the Florida Everglades. Alligator Alcatraz - that is the official name - was assembled in eight days and opened on July 1. President Donald Trump visited the remote site on opening day, built at an old runway near the Miami-Dade and Collier county line.

On Wednesday night, workers replaced the signs in front of the training facility with ones that read "Alligator Alcatraz."

The first group of immigrants has arrived at a new detention center deep in the Florida Everglades that officials have dubbed “Alligator Alcatraz,” a spokesperson for Republican state Attorney General James Uthmeier told The Associated Press.
