The purpose of this legislation is to allow certain states, specifically those bordering Canada and Mexico, to take actions on federal land to enhance the security of the United States' international borders. The bill is called the "Creating Obstructions Necessary To Address Illegal and Nefarious Entry Rapidly Act," or the "CONTAINER Act." The key provisions of the bill include allowing border states to place temporary, movable structures on federal land without needing special authorization from federal agencies.
