The main purpose of this legislation is to allow members of Congress and their staff to access certain Indian lands along the U.S.-Mexico border. This access is intended to help them evaluate national security and public safety concerns related to the international boundary. Key provisions of the legislation include granting lawful access to any Indian reservation that is located within 50 or more contiguous miles of the U.S.-Mexico border. This access is not only for the land itself but also includes any roadways or easements within those areas.
