3 arrested at border wall construction site as Arizona borderlands protests continue

Pieces of a cottonwood lay along the side of the road at the U.S.-Mexico border near Nogales, Arizona, in July 2026 after being chopped down earlier in the week by contractors.

Three border wall protesters were arrested Monday afternoon along a remote stretch of the Arizona-Mexico border, where the Trump administration is building a double steel wall.

The Cochise County Sheriff’s Office says protesters were arrested on disorderly conduct charges just east of the Santa Cruz County line, where a group had gathered inside a wall construction zone.

In a statement about the arrests on Facebook, the Sheriff’s Office said deputies responded to a reported trespassing incident after protesters refused to leave the construction site.

“Several individuals subsequently moved farther into the restricted area and accessed construction materials intended for use in the border wall project,” read a statement. “Their actions created a safety and security concern for the protesters, construction personnel, private security personnel, and responding law enforcement officers.”

Video shared by protesters show a person dressed in a jaguar costume and another dressed as a local migratory bird called a Yellow-billed cuckoo. Both are cross-border, endangered species that environmentalists say would be cut off from water and mates in Mexico if the walls are built.

Protesters have been sitting in an old growth cottonwood tree several miles west of where this week’s arrests took place for nearly two months to prevent its demolition.

That protest began after three other trees, each estimated to be as much as 250 years old, were torn down by wall contractors. More wall construction is moving forward farther west inside Organ Pipe Cactus National Monument and along the 62 miles of border inside the Tohono O’odham Nation.

Billions in funding is earmarked for the border wall and other Department Homeland Security projects under a massive GOP spending bill passed last year.
