The Trump administration begins construction of an Arizona section of the border wall, a move the Tohono O’odham Nation opposes. Multiple outlets report that this week construction activity occurs on or near tribal land, where the tribe says federal personnel accompany contractors during the work.

The Tohono O’odham Nation argues the project would harm the reservation and its cultural and geographic landmarks. One account says the tribe objects to the construction because it is accompanied by armed federal agents and involves alleged trespassing. Another describes the tribe’s concerns about “significant devastation,” including damage to mountain peaks that the tribe regards as sacred, as well as changes to the tribe’s boundaries.

Across reporting, the dispute centers on access to tribal territory and the potential impacts of the wall on the reservation’s landscape and governance, with the administration proceeding with construction despite the tribe’s objections.
