What happened

In August, the Pentagon administered polygraph tests to about 50 people, including Joint Staff members, some U.S. Central Command officials, and other combatant commanders, in what officials called an extremely rare high-volume investigation of classified leaks to journalists about U.S. munitions stockpiles during the war with Iran. Joint Chiefs Chairman Gen. Dan Caine was not tested, the FBI was not involved, sources said no one failed questions about leaking to the media, and officials noted that only a very small set of people had access to the details, raising concern that someone could be acting as a foreign intelligence asset. The tests followed reporting that the conflict had rapidly expended advanced weapons including long-range missiles and Patriot interceptors, a July Center for Strategic and International Studies estimate that the United States had used about two-thirds of its pre-war Patriot and THAAD inventories, and a Pentagon plan to buy nearly 14,000 additional PAC-3 and THAAD components. In July, Defense Secretary Pete Hegseth announced a joint Pentagon–Justice Department task force to identify and prosecute suspected leakers, saying leaked information “risks lives”; President Trump, whom CBS News sources said was furious about the disclosures, denied any shortage, writing that “treasonous SCUM” who “refuse to accurately report” on the Iran operation faced “virtually unlimited amounts of Mid to High Grade Ammunition,” after pledging a month earlier that such leakers were being “hunted down.” Chief Pentagon spokesman Sean Parnell declined to discuss the inquiry, saying the department “takes all leaks of classified national security information extremely seriously.”
Sourcing check · Mostly on the record · 3 articles

2 of 3 articles cite a named source for the story. It started with a New York Times report citing unnamed sources; a named source appeared 2 hours later. Most articles credit New York Times rather than reporting it themselves.

What these terms mean and how they're counted
On the record · names a source 2 of 3
On the record means the article cites a source by name for the story's main claim: a person, or an institution speaking officially, such as a company statement or a named agency's spokesperson. The opposite is an unnamed source. The count is how many of the counted articles cite at least one such source; the names are everyone named across them, each once however the articles spell it. Here: CBS News, Sean Parnell and Center for Strategic and International Studies
Primary evidence · cites a document or data 0 of 3
Primary evidence means the article cites a record you could check yourself: a court filing or ruling, a dataset or report, a recording or transcript, an official statement or press release, market data. A quote is not a document. The count is how many articles cite one. Here: None cited.
Credits another outlet 3 of 3
The article says the story comes from another outlet's reporting (“first reported by Reuters”). Those articles relay the story; they are not independent confirmation. Here: New York Times, CBS News, The New York Times
Unnamed sources 1 of 3
The main claim is attributed to people who are not identified: “people familiar with the matter”, “officials said”. The count is how many articles do this.
How it developed
When the first report landed and whether it named anyone; when the first named source and the first document appeared. Here: First report Sep 5, 14:34 UTC by The Hill, crediting New York Times, with no named source. First named source 2 hours later, from Washington Examiner.

Unpacked

Left-leaning coverage reports a Pentagon leak hunt aimed at Joint Staff officials after stories on the Iran war and never says how the polygraphs turned out. Right-leaning coverage includes the result: the Washington Examiner reports that no one failed the questions about talking to the press. That silence leaves readers of the Times with an unfinished dragnet instead of a round of tests that cleared the people who sat for them. The two sides cannot agree whether the sweep was historic or routine. Left-leaning coverage at the New York Times calls the episode an "unparalleled inquiry." Right-leaning coverage in the Washington Examiner treats polygraph testing as a familiar clearance ritual rather than a break from practice, noting that high-level clearance holders already face such tests on a multi-year cycle. If those exams found no leaker, who still had access to the classified stockpile numbers that reached the press?
Bottom line

If you only read the New York Times, the Pentagon’s munitions-leak polygraphs still look like an open hunt, not a round that cleared the officials who took them.

The Left View
Left-leaning outlets framed the episode as a “major” and “unparalleled” leak hunt that reached “some of the U.S. military’s highest-ranking officials” after reporting on “diminished” and “dwindling” weapons stockpiles. The New York Times and The Hill treated those news reports as the relevant backdrop and presented the polygraphs as a sweeping internal effort to determine who had spoken to journalists.
The Right View
Right-leaning outlets framed the tests as a “hunt for leakers” and a reported “crackdown” on classified operational disclosures. The Washington Examiner noted that periodic polygraphs are “not out of the ordinary” for clearance holders, that no one failed leak-related questions, and that the Pentagon regards securing classified information as “critical to ensuring the security of the United States and of our troops.” The Daily Caller emphasized Trump’s denial of a shortage and his “treasonous” label for the reporting, while also citing the CSIS depletion estimate and the American Psychological Association’s warning that polygraphs can produce false positives.
Our Take (balanced)
The left’s strongest argument, grounded in the “unparalleled” scale, is that the Pentagon mounted an extraordinary investigation of its own top staff because journalists had reported wartime munitions shortages that the CSIS estimate and the restocking order already made difficult to dismiss. The right’s strongest argument is that the material was classified, known to a very small circle, and treated by Hegseth as information that “risks lives,” with officials also concerned someone could be a foreign intelligence asset—grounds for hunting leakers irrespective of the public inventory dispute. The central unresolved tension is whether the mass polygraphs were a legitimate security investigation into classified leaks that could endanger troops, or a political crackdown on reporting that contradicted the administration’s account of munitions supplies.
