The Tohono O’odham Nation has warned that federal border-wall contractors may attempt to enter its reservation without authorization, prompting “No Trespassing” signs across Nation lands and putting Tribal police on alert.
The dispute is rooted in a border drawn through an existing Indigenous homeland.
The international boundary cuts through a wider O’odham homeland spanning present-day Arizona and Sonora, Mexico. Distinct O’odham peoples, including Tohono O’odham and Hia-Ced O’odham, have longstanding ties to lands across this region, and O’odham communities continue to live on both sides of the border today.
In its federal lawsuit, the Nation says the border has long divided O’odham communities and families. It also says an agreement with Border Patrol allows Tribal members from either side to cross through three traditional gates, with additional crossings coordinated for ceremonies, gathering and other cultural purposes.
Vice Chairwoman Carla Johnson said a permanent wall would “separate our families, desecrate our sacred sites and waters and harm our natural environment.”
The Nation is not opposed to border enforcement. It has worked with federal agencies for decades on vehicle barriers, patrol roads, surveillance technology and Border Patrol facilities. The Shadow Wolves, a Native tactical unit based on the Nation, use traditional tracking and modern technology to interdict drug and human smuggling.
Earlier this year, CBP acknowledged that a contractor damaged part of Las Playas Intaglio, an approximately 1,000-year-old O’odham cultural site.
The Nation sued DHS in June, arguing construction would unlawfully take reservation land and authorize trespass. DHS has said it values its relationship with the Nation and is focused on “open communication and minimizing impacts.”
CBP told KJZZ on Aug. 11 that it is aware of the Nation’s trespass warning but declined to comment on the claim because of ongoing litigation.
“We have been left with no other choice but to file suit to protect our land, our culture, and our rights,” Chairman Verlon Jose said.
