Pentagon polygraphs top military brass over classified munitions leaks
Leaked information risks lives.
Mark
Why would the Pentagon test dozens of officials at once? Doesn't that seem like overkill for a leak investigation?
Mimi
The scale tells you how seriously they took this. When access to classified information is restricted to a very small group, and that information ends up in the media, the concern isn't just about carelessness—it's about whether someone with clearance is working for a foreign intelligence service. That's a different kind of threat.
Luke
But here's what we don't know: we have no idea what the actual leak was, or how damaging it was. We know it involved munitions stockpiles and the Iran war, but the specifics are still classified. So we're evaluating the response without seeing the actual threat.
Mark
Did they find anything? Any actual leakers?
Mimi
No one failed the polygraph questions about media leaks. So either the leaker wasn't in that group of people tested, or the polygraph didn't catch them, or there's something else going on.
Luke
And that's important to note—polygraphs aren't foolproof. They measure physiological responses, not truth. The fact that no one failed doesn't necessarily mean no one leaked.
Mark
What about Hegseth's history with this? It sounds like he's been aggressive about leaks before.
Mimi
Very aggressive. Last year he threatened to polygraph Admiral Grady over a different leak, and he blocked the promotion of Lieutenant General Sims, who he also threatened. Sims ended up retiring.
Luke
But we should be careful here—Hegseth threatened Grady, but Grady was never actually tested. And with Sims, we know Hegseth didn't promote him, but we don't know if that was solely because of the leak threat or if there were other factors. The reporting tells us what happened, but not necessarily why.
Mark
Is this legal? Can a defense secretary just order mass polygraphs?
Mimi
Technically yes, but with limits. Federal law says the secretary has to use polygraphs in a responsible and effective manner, and in most cases the person being tested has to consent or request it. There are exceptions for serious security investigations.
Luke
The question is whether this summer's testing met those legal standards. We don't have confirmation that everyone tested actually consented, or that the investigation met the legal threshold for mandatory testing. That's a gap in the reporting.
El Pulso
- Classified details about U.S. munitions expenditure during the Iran war appeared in media reports, triggering presidential fury and a counterintelligence alarm over who could have had access to such tightly held information.
- The Pentagon responded with a mass polygraph sweep of several dozen senior military officials — a step so unusual that those briefed on it described it as extraordinarily rare even by the standards of a security-conscious institution.
- Investigators' deepest fear was not a disgruntled official talking to reporters, but the possibility that someone with high-level clearance was operating as a foreign intelligence asset.
- No one failed the questions targeting media leaks, leaving the investigation unresolved and the source of the breach still unknown.
- Defense Secretary Hegseth formalized the pressure campaign by establishing a joint Pentagon-Justice Department task force and granting broad authority to demand records from personnel within 48 hours.
- The crackdown arrives alongside a pattern of Hegseth personally threatening officials with polygraphs — a posture that has already reshaped careers and signaled that leak enforcement will be wielded as an instrument of institutional discipline.
In the shadow of an ongoing war, the Pentagon turned its gaze inward this summer, subjecting dozens of its most senior military officials to polygraph examinations in a rare and sweeping effort to trace the source of classified weapons information that had surfaced in public reporting. The investigation reflects an enduring tension at the heart of democratic governance — between the state's need for secrecy and the public's claim to knowledge — while raising the more unsettling possibility that the breach may have served a foreign power rather than an informed citizenry. That no one failed the leak-related questions has not resolved the matter so much as deepened it, leaving the search for accountability suspended between suspicion and silence.
Over the summer, the Pentagon undertook one of the most expansive internal security investigations in recent memory, polygraphing several dozen senior military officials in connection with leaks of classified information about U.S. weapons stockpiles. Officials familiar with the matter described the mass examination of top-ranking brass as extraordinarily rare. The specific concern was highly classified data about sophisticated munitions — including the rate at which advanced weapons were being consumed during the Iran war — that had appeared in press reporting. President Trump was said to be furious. Because access to that information was restricted to a very small circle, investigators could not rule out the possibility that someone with clearance was acting as a foreign intelligence asset rather than simply speaking to journalists.
The polygraph sessions drew in officials from U.S. Central Command and other combatant commands, though not all senior leadership was included — Joint Chiefs Chairman General Dan Caine was not among those tested. The FBI played no role; the military conducted the examinations through its own investigators. According to two officials with knowledge of the results, no one failed the questions designed to detect media leaks, leaving the investigation without a clear resolution.
Defense Secretary Pete Hegseth moved swiftly to institutionalize the response. In July, he announced a joint Pentagon-Justice Department task force to identify and prosecute leakers, and granted the Pentagon's Office of General Counsel sweeping authority to demand records from personnel within two days. The announcement followed the Justice Department's short-lived subpoenas of New York Times reporters — later withdrawn after judicial scrutiny — over reporting on security concerns surrounding a Qatari-donated aircraft intended for presidential use.
Hegseth's aggressive stance on leaks predates this investigation. After details of a classified China briefing arranged for Elon Musk leaked in early 2025, he reportedly confronted Admiral Christopher Grady, then acting chairman of the Joint Chiefs, demanding proof Grady was not the source and threatening him with a polygraph. Grady was never tested, but Lieutenant General Doug Sims faced a similar threat and retired last September after Hegseth declined to promote him. Federal law permits secretaries of defense to direct polygraph-based counterintelligence investigations but requires procedural safeguards, including consent in most circumstances, and mandates congressional reporting — constraints that frame, if not fully contain, the authority Hegseth has been willing to exercise.
The Pentagon conducted an unusually broad polygraph investigation over the summer, testing several dozen of the military's most senior officials in connection with leaks of classified information about the nation's weapons stockpiles. The scale of the examination was extraordinary—officials briefed on the matter told CBS News that mass polygraphing of top-ranking military brass is extremely rare, even though routine polygraph testing is standard procedure for those with access to the most sensitive national security materials.
The investigation centered on highly classified details about sophisticated munitions that had appeared in media reporting, particularly regarding the rate at which the U.S. was expending advanced weapons during the Iran war. President Trump was reportedly furious about the disclosures. Because access to the specific munitions information was restricted to a very small group of people, investigators were concerned about whether someone with clearance might be acting as a foreign intelligence asset. The polygraph questions ranged broadly across national security matters, though the specific focus was whether any of those tested had leaked to journalists. According to two officials with knowledge of the results, no one failed the questions designed to detect media leaks.
The testing included officials from U.S. Central Command and other combatant commands, though not all senior military leadership was included. General Dan Caine, the chairman of the Joint Chiefs of Staff, was not polygraphed, according to a senior Pentagon official. The FBI did not conduct these examinations; the military used its own investigators. Pentagon spokesman Sean Parnell declined to discuss the specifics of the investigation, stating only that the Department takes leaks of classified national security information extremely seriously and investigates them accordingly.
Defense Secretary Pete Hegseth moved quickly to formalize the leak investigation. In July, he announced that the Pentagon and Justice Department had formed a joint task force specifically to identify and prosecute suspected leakers. Hegseth gave the Pentagon's Office of General Counsel, led by Earl Matthews, broad authority to demand information and records from Pentagon personnel, with a requirement that officials respond within two days. "Leaked information risks lives," Hegseth said when announcing the task force, emphasizing the urgency of providing law enforcement with actionable intelligence as quickly as possible.
The announcement came days after the Justice Department had subpoenaed several New York Times reporters over their reporting on security shortcomings aboard a new Air Force One aircraft donated by Qatar to President Trump. The Justice Department later withdrew those subpoenas after a federal judge questioned prosecutors during a contentious court hearing about why they had issued the subpoenas before conducting further investigative steps.
Hegseth's aggressive posture on leaks is not new. Last year, after details of a classified briefing on China that had been arranged for Elon Musk at the Pentagon leaked to the press, Hegseth was reportedly furious. According to the Wall Street Journal, he shouted at Admiral Christopher Grady, then the acting chairman of the Joint Chiefs, demanding evidence that Grady wasn't the source of the leak from the March 21, 2025, briefing. The Journal reported that Hegseth threatened to subject Grady to a polygraph examination. Grady was never actually tested, but Hegseth did threaten Lieutenant General Doug Sims, the director of the Joint Staff, with the same measure. Sims retired last September after Hegseth decided against promoting him to four-star general.
Under federal law and Pentagon regulations, secretaries of defense have authority to direct counterintelligence investigations that include polygraph examinations, but the law imposes restrictions on when polygraphs may be used and requires procedural safeguards. In most cases, the person being examined must consent to or request the test, particularly when investigators are trying to resolve serious information uncovered during a security investigation or when someone wants to clear themselves of allegations. Hegseth is required by law to ensure that polygraph examinations are used in a responsible and effective manner and must report on polygraph use to Congress.
