Construction of a new 100-kilometer border wall segment with Mexico began in Arizona on the territory of the Tohono O'odham Nation, driven by the administration of US President Donald Trump. [^6]

The project, identified as the Tucson 5 wall, is a 62-mile (100-kilometer), double-layer steel-and-concrete barrier about 30 feet (9.1 meters) high built near the reservation. [^3]

The Tohono O'odham Nation argued that the Tucson 5 wall threatens its sovereignty, the movement of its members across the U.S.-Mexico border, and cultural and spiritual sites. [^1] The nation's territory spans about 2.8 million acres (1.13 million hectares) in southwestern Arizona and includes roughly 39 miles (62 kilometers) of border with Mexico, and its members cross the border for religious ceremonies, pilgrimages, and family reunions.
