The Tohono O'odham Nation has initiated legal and physical resistance against U.S. border wall construction on its Arizona reservation. In July 2026, the tribe filed a lawsuit in a Washington, D.C. federal court, alleging that the Department of Homeland Security is illegally seizing tribal land and threatening sacred sites. The tribe argued that construction would cause “irreversible cultural damage” and suggested that modern surveillance technology should be used instead of a physical barrier. By August 2026, the conflict escalated as a federal judge, Richard Leon, denied the tribe’s request to halt construction. The judge ruled that national security and foreign policy considerations regarding border security outweighed the tribe’s concerns regarding land use and trespassing. Following this ruling, U.S. Customs and Border Protection (CBP) resumed the ‘Tucson 5’ project, a 100-kilometer construction effort. CBP Commissioner Rodney Scott defended the infrastructure as necessary to close a remote desert corridor used for drug trafficking and cartel activities. However, tribal leaders have denounced the project as a territorial invasion and criticized the federal government for failing to conduct meaningful consultations. In response to ongoing work, tribal leaders have issued warnings to federal contractors against unauthorized entry onto reservation land, threatening fines and equipment impoundment.
