A decision about halting construction and operation at Alligator Alcatraz is expected before the end of the day.

Miami-Dade County Mayor Daniella Levine Cava, who has objected to the facility and asked for access to "monitor" it, said she "welcome (d) the court’s decision to halt construction at Alligator Alcatraz — an overdue and necessary step."

Construction of a makeshift immigrant detention center in the Florida Everglades dubbed “ Alligator Alcatraz ” could be halted indefinitely as a federal judge considered Wednesday whether the hasty development on sensitive wetlands violated environmental laws.
