Environmental groups are suing to block a plan to build an immigration detention center known as “Alligator Alcatraz” in the Florida Everglades. 

Friends of the Everglades and the Center for Biological Diversity on Friday filed a lawsuit in the U.S. District Court for the Southern District of Florida against the Department of Homeland Security, U.S. Immigration and Customs Enforcement, the Florida Division of Emergency Management, and Miami-Dade County to block the build-out of the immigration center.
