(AP) — 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.

“People are there,” Press Secretary Jae Williams said, though he didn’t immediately provide further details on the number of detainees or when they arrived.

“Next stop: back to where they came from,” Uthmeier said on the X social media platform Wednesday.

“Stood up in record time under @GovRonDeSantis ‘ leadership & in coordination with @DHSgov & @ICEgov, Florida is proud to help facilitate @realDonaldTrump ‘s mission to enforce immigration law,” the account for the Florida Division of Emergency Management posted to the social media site X on Thursday. Requests for additional information from the office of Republican Gov. Ron DeSantis and FDEM, which is building the site, were not returned early Thursday afternoon.
