Department of Homeland Security (DHS) Secretary Markwayne Mullin addressed reports regarding the acquisition of a military-grade weapon known as the Active Denial System (ADS) during a recent statement. The device, which was transferred to the department from the Pentagon, is designed to project an invisible beam of electromagnetic waves. When directed at a target, these waves create a sensation of intense heat, intended to deter individuals from a specific area without causing permanent injury.

Secretary Mullin stated that the department is "always evaluating technology on the border," framing the acquisition as part of a broader effort to modernize border security tools. While the DHS has confirmed the receipt of the technology, the department has not provided a specific timeline or operational plan for its deployment. The Active Denial System has historically been a subject of debate regarding its potential for misuse and the ethical implications of using non-lethal, pain-inducing technology on civilians or migrants. Critics often point to the psychological impact of such devices, while proponents argue they provide a necessary, non-lethal alternative to traditional force. As of now, the DHS has maintained a general stance on testing and evaluation, leaving the specific policy regarding the weapon's use at the U.S.-Mexico border currently undefined.
