Officials of the Tohono O’odham Nation in Arizona are raising alarms over what they call a violation of tribal law, alleging that armed, masked Customs and Border Protection (CBP) agents escorted border wall construction contractors through the reservation earlier this week. The incident marks the latest flashpoint in the tribe’s ongoing legal battle to halt a 62-mile border infrastructure project along the Roosevelt Easement, a narrow strip of federally owned land between the reservation’s southern boundary and the U.S.-Mexico border.
According to the tribe, approximately 20 masked, armed CBP agents from the Tucson Border Patrol Sector entered the Tohono O’odham Nation on Tuesday to escort the contractors, who then began pre-construction activities on federal lands after using the reservation to reach the easement. The tribe argues that the contractors were trespassing under the Tohono O’odham Code, Title 4, Chapter 2, which addresses “Civil Trespass; Removal and Exclusion of Nonmembers.” The tribe’s public announcement said the contractors began work at three sites within the easement, using drill trucks to conduct soil sampling and other activities.
The development comes just weeks after a federal judge denied the tribe’s request for a preliminary injunction to stop the project, allowing CBP to move forward while the underlying lawsuit continues. The project, known officially as Tucson 5, involves the installation of additional border wall and smart technology, including lighting and camera suites, along the 62-mile stretch.
BORTAC and BIA Officers Involved
Tribal officials say the CBP team sent to escort and provide security for the contractors included a contingent of Border Patrol agents assigned to the agency’s BORTAC Tactical Team, along with several Bureau of Indian Affairs (BIA) officers. The tribe also reported that a tethered balloon is being used to provide additional monitoring of the project area.
The Tohono O’odham Nation has long opposed the border wall project, citing concerns about the impact on tribal lands, cultural resources, and the community’s cross-border ties. The reservation spans 2.8 million acres along the U.S.-Mexico border in southern Arizona, and several thousand tribal members reside in seventeen communities in Mexico, directly across the border from the reservation.
Legal Setback for the Tribe
In early August, U.S. District Judge Richard Leon denied the tribe’s request to halt CBP’s plan, rejecting the assertion that the project would alter the established boundaries of the reservation. Leon ruled that the tribe’s lawsuit was “unlikely to succeed on the merits” of the case, delivering a major victory for the Trump administration and clearing the way for a renewed push by CBP to complete the project.
Prior to the alleged trespassing incident, CBP Commissioner Rodney Scott had announced that the agency would move forward with the project after the injunction request was denied. A source within the Department of Homeland Security, who was not authorized to speak to the media, said most equipment needed for the initial phases of the project has already been moved through the reservation and onto the federally owned easement. The source added that CBP and the Border Patrol continue to engage with tribal officials to address concerns amicably, but remain determined to complete the project.
The Roosevelt Easement, established in 1907, designates a 60-foot-wide strip of land as federal property, set aside to combat smuggling. The easement runs along the border adjacent to the 62-mile international boundary between the Tohono O’odham reservation and Mexico. This historical designation complicates the tribe’s legal standing, as the land in question falls under federal jurisdiction.
Funding and Next Steps
The project is funded through provisions in the One Big Beautiful Bill, which authorized $46.5 billion for border wall construction and border infrastructure improvements. The Trump administration has prioritized border wall expansion, and the Tucson 5 project is a key component of that effort.
The tribe’s latest complaint underscores the deepening rift between the federal government and tribal authorities over the project. While CBP maintains it is operating within federal law and on federal land, the Tohono O’odham Nation insists that the escorted entry through the reservation violates its sovereignty and legal codes.
As the lawsuit makes its way through the courts, the tribe faces an uphill battle, but its leaders have vowed to continue fighting the project. The alleged trespassing incident on Tuesday adds a new layer of tension to an already fraught situation, raising questions about the limits of federal authority on tribal lands and the lengths to which the administration will go to advance its border agenda.
Breitbart Texas first reported on the tribe’s injunction denial in early August, and the latest developments were detailed in the tribe’s public announcement on Tuesday. The Tohono O’odham Nation has not indicated whether it plans to file additional legal action over the alleged trespassing, but the dispute is likely to intensify as construction activity ramps up.
