CBP defends border wall progress and autonomous tower testing, cites drug‑interdiction gains

CBP told the House Homeland Security Subcommittee that recent investments in physical barriers and detection technology are helping the agency concentrate personnel, improve inspections and heighten drug interdiction efforts.

Commissioner Scott said the agency is "ahead of schedule and below budget" on border construction and gave a current tally of work: roughly "almost 50 miles of new construction of primary border wall, about 5.5 of Bowie barrier, and about 13.2 of secondary barrier." He described the wall as integrated with technology and said it frees agents to focus on interdiction and ports of entry.

On towers and autonomous detection, Scott said several companies have passed an autonomy test and that CBP is using AI and third‑party validation in phased field testing. "If an agent wants to take over that tower, they can," he said, describing a goal of delivering real‑time cues to agents' field devices rather than requiring an agent to watch a fixed screen.

Members asked about testing, usability and procurement timelines; Scott said rollout is phased and emphasized agent testing in the field before full procurement, and promised to provide more detailed timing and procurement plans to members.

On interdiction, witnesses said better inspection technology and focused intelligence targeting account for increased seizures; CBP said the goal is to prevent narcotics from reaching the street rather than simply recording higher seizure weights.

The committee pressed for continued field validation and for assurances that tower systems will meet agents' operational needs before large contracts are signed.
