Environmental groups have asked a federal appellate court panel to lift its temporary halt on closing an immigration detention center in the Florida Everglades. Known as "Alligator Alcatraz," the center remains open due to arguments by Florida and the Trump administration. They claimed the state hadn't gotten federal reimbursement, so it wasn't required to follow federal environmental law. On Tuesday, during a hearing in Miami, the judges questioned how much control the federal government had over the state-built facility. Florida was notified in late September of $608 million in federal funding approval. The environmental lawsuit was one of three federal challenges to the facility since it opened.
