Trucks were seen leaving "Alligator Alcatraz" in Florida as the facility is shutting down.

The facility was already being emptied of detainees as of last week, according to an email exchange shared with The Associated Press on Wednesday. The executive director of the Florida Division of Emergency Management, Kevin Guthrie, said on Aug. 22 “we are probably going to be down to 0 individuals within a few days,” in a message to a rabbi about chaplaincy services.

Funding is central to the federal government's arguments that Williams' order should be overturned by an appellate court.

Homeland Security attorneys said in a court filing this week that federal environmental law doesn't apply to a state like Florida, and the federal government isn't responsible for the detention center since it hasn't spent a cent to build or operate the facility, even though Florida is seeking some federal grant money to fund a portion of the detention center.

“No final federal funding decisions have been made,” the attorneys said.

Almost two dozen Republican-led states also urged the appellate court to overturn the order. The 22 states argued in another court filing that the judge overstepped her authority and that the federal environmental laws only applied to the federal agencies, not the state of Florida.

Republican Gov. Ron DeSantis ’ administration is preparing to open a second immigration detention facility dubbed “Deportation Depot” at a state prison in north Florida.

Civil rights groups filed a second lawsuit last month against the state and federal governments over practices at the Everglades facility, claiming detainees were denied access to the legal system.

A third lawsuit by civil rights groups last Friday described “severe problems” at the facility which were “previously unheard-of in the immigration system.”
