60 Minutes alleges CIA cover-up after report of microwave weapon purchase

Former CIA officer Marc Polymeropoulos accuses the agency of a "massive cover-up" after suffering mysterious brain injuries, as a 60 Minutes investigation reported that Homeland Security agents in 2024 purchased a previously unknown miniaturized microwave weapon. The CBS segment said the acquisition was financed in part by the Defense Department and cited intelligence officials pledging a comprehensive review amid an ongoing health crisis for personnel.

"60 Minutes has learned new details from three independent sources from different government agencies about a classified mission involving Homeland Security agents who, in 2024, purchased a previously unknown miniaturized microwave weapon from a complex Russian criminal network," the program reported. "Over $15 million in funding for the mission came from the Pentagon," the segment added.

CBS attributed the procurement and funding to unnamed government sources and noted significant caveats. "While the specific device they purchased was not linked to any one AHI attack, it contains the pulsed microwave technology that could potentially cause Havana Syndrome symptoms, sources say." The network also reported internal skepticism inside the CIA, quoting agency personnel who believed "that any microwave weapon capable of causing the symptoms described by Havana Syndrome victims would need to be the size of a truck, which means it wouldn't be plausible in the hundreds of cases."

The allegations stitch together several contested threads in an investigation that has roiled Washington for more than a decade. U.S. government and military officials have reported mysterious illnesses, commonly labeled Havana Syndrome and now referred to in official settings as Anomalous Health Incidents, or AHI. Polymeropoulos, who worked at the agency nearly 30 years and rose to an executive level, is identified in the report as among those seeking vindication after unexplained injuries; the segment and the user-supplied summary state his injuries may be "possibly tied to a US military-tested device," though CBS did not link the 2024 purchase to any single AHI incident.

The reporting raises immediate policy and oversight questions. A classified mission that routed more than $15 million in Pentagon funds into a procurement from a "complex Russian criminal network," as reported, exposes vulnerabilities in interagency controls, contracting oversight and the use of classified funding streams. It also sharpens scrutiny of how intelligence agencies investigate and disclose risks to personnel. The CBS investigation was credited as a collaboration with Michael Weiss at TheInsider.ru and was presented by Scott Pelley on March 8, 2026.

Legal and congressional actors will now face choices about how to press for documentation and accountability. The identities of the "three independent sources" cited by CBS remain undisclosed, and the network did not present procurement records in the material summarized here. The lack of a direct technical link between the device described and any single AHI case, coupled with CIA internal doubts about the plausibility of a compact microwave weapon explaining hundreds of illnesses, leaves the public with a complicated factual picture.

Intelligence officials, cited in the material, have pledged "comprehensive review amid ongoing health crisis for personnel." That review will determine whether the new procurement details represent an operational misstep, a legitimate but poorly documented countermeasure, or an explanatory thread that does not account for the broader pattern of reported injuries. Regardless, the revelations will increase pressure for transparent oversight of classified programs that bear directly on the health of U.S. personnel and on public confidence in national security institutions.
