Classified secrets about America’s weapons stockpiles were bleeding out to the press.
President Trump was furious, and somebody inside the building was going to answer for it.
And now the full picture of what Pete Hegseth did to hunt down the leakers is coming to light — and it’s bigger than anyone reported.
Dozens Strapped to the Chair
Several dozen of the highest-ranking officials in the US military were subjected to polygraph tests as part of a sweeping leak probe, after highly sensitive classified details about the nation’s stockpiles of sophisticated weapons turned up in media reports, according to US officials briefed on the matter who spoke to CBS News.
Three sources told CBS News that President Trump was furious about the leaks.
The access list for this information was extremely tight. According to one of the sources, the circle of people who could have seen the classified munitions data was very small, and investigators were concerned about whether anyone in that group could potentially be acting as a foreign intelligence asset.
That last part deserves a moment. Foreign intelligence asset. Not just a disgruntled bureaucrat with a press contact. The concern, according to sources, was that someone inside the US military with access to sensitive weapons data might have been working for an outside power.
Polygraph tests are part of the routine cadence for top military and civilian officials, but officials told CBS News the mass volume of people pulled in for testing in this case was extremely rare.
The FBI did not conduct the tests, according to people with direct knowledge of the matter, because the military has its own investigators. Federal law allows defense secretaries to direct counterintelligence investigations that may include polygraphs, though examinations are subject to procedural safeguards and consent requirements.
And according to two sources, no one failed the questions meant to determine if these officials leaked to the media.
Hegseth Wasn’t Playing Around
The polygraph dragnet didn’t come out of nowhere. It was the culmination of months of escalating pressure from Defense Secretary Pete Hegseth, who had already made clear he intended to find whoever was feeding classified information to reporters.
The Wall Street Journal had previously reported that Hegseth erupted at Adm. Christopher Grady, the then-acting chairman of the Joint Chiefs of Staff, after details of a planned classified briefing on China set up for Elon Musk at the Pentagon leaked to the press. The briefing in question was reportedly scheduled for March 21, 2025.
Citing two anonymous people familiar with the exchange, the Journal reported Hegseth yelled at Grady: “I’ll hook you up to a f—ing polygraph!”
Grady was never actually subjected to a polygraph examination. But Lt. Gen. Doug Sims, who served as director of the Joint Staff, was also accused of leaking and threatened with a polygraph, according to the Journal. Hegseth decided against promoting Sims to four-star general, the New York Times reported. Sims retired last September.
In July, Hegseth announced that the Pentagon and the Justice Department had formed a joint task force specifically to identify and prosecute people suspected of leaking sensitive government information to the press, significantly expanding an effort that had begun inside his own office.
Hegseth also authorized the Pentagon’s Office of General Counsel to seek records and assistance for leak investigations, with personnel directed to prioritize those requests within two days.
Not every senior official got swept up. Joint Chiefs Chairman Gen. Dan Caine was not polygraphed, according to a senior Pentagon official.
Chief Pentagon spokesman Sean Parnell put out a statement that didn’t deny any of it: “The Department does not comment on internal personnel or investigative matters but takes all leaks of classified national security information extremely seriously and investigates accordingly. Securing classified information is critical to ensuring the security of the United States and of our troops deployed around the world.”
The Leak Problem Is Bigger Than the Press Is Telling You
The media coverage of this story has focused almost entirely on the drama — Hegseth yelling at admirals, generals strapped to polygraph machines, the sheer scale of the testing operation. And sure, that’s a story.
But the underlying issue is getting buried.
Classified details about America’s weapons stockpiles — specifically, how fast the US was burning through some of its most advanced and finite munitions — were making their way into print. The New York Times was first to report on the polygraph tests themselves, but CBS News and other outlets had earlier reported the substance of what was leaking: the rapid pace at which the US was expending sophisticated weapons.
That’s not a minor embarrassment. That’s the kind of information that tells adversaries exactly how long America can sustain a military operation before running dry.
And someone with access to that information decided to hand it to journalists.
The permanent bureaucracy inside the Pentagon has a long and documented habit of leaking to the press when it disagrees with civilian leadership. Career officials who outlast administrations have used anonymous sourcing as a tool to shape policy, undercut decisions they oppose, and signal to the press corps which direction they want coverage to go. This is not a new phenomenon. It predates Hegseth, it predates Trump, and it has never been treated with the seriousness it deserves — until now.
Hegseth is doing something the defense establishment hasn’t seen in a long time: a civilian secretary who actually intends to find out who is talking and hold them accountable. The joint task force with the Justice Department isn’t a press release. It’s a real enforcement mechanism with prosecutors attached to it.
The fact that no one failed the polygraph questions about media leaks doesn’t mean the investigation is over. It means the investigation hasn’t found its answer yet — and that Hegseth isn’t stopping.
There’s also a broader pattern worth noting. The same media outlets now writing breathlessly about the “unprecedented” use of polygraphs at the Pentagon are the same outlets that published the leaked classified information in the first place. They benefit from the leaks, they protect their sources, and then they cover the investigation into those leaks as an abuse of power. That’s a remarkable position to hold with a straight face.
Classified weapons data doesn’t belong in newspaper columns. The people who put it there — whoever they are — endangered American troops and handed strategic intelligence to anyone paying attention. Hegseth is right to hunt them down. The question is whether the system will actually let him finish the job.
