Environmentalists and the Miccosukee Tribe are urging U.S. District Judge Kathleen Williams to issue a preliminary injunction halting operations and construction at the site.

Last week, US District Judge Kathleen Williams ordered a 14-day halt on additional construction at the site while witnesses testified at a hearing, part of a lawsuit seeking to halt operations and further construction.

A federal judge will hear closing arguments in a hearing over whether to stop construction indefinitely at “Alligator Alcatraz.”
