Pentagon Leak Hunt Escalates as Polygraphs Fail to Reveal a Suspect
The Pentagon’s response to leaks about dwindling weapons stockpiles has moved from internal scrutiny to an unusually broad hunt for a suspect, yet the effort appears to have yielded more alarm than answers.

Several dozen senior military and civilian officials were subjected to polygraph examinations earlier this summer, including personnel connected to U.S. Central Command and other combatant commands. The scale was highly unusual: while officials with access to top-secret programs periodically undergo testing, the mass examinations reportedly signaled a targeted investigation rather than routine clearance checks.

The administration’s concern was not limited to unauthorized contact with journalists. According to officials briefed on the matter, a small number of people had access to classified information about finite munitions, prompting questions about whether a foreign intelligence asset might be involved. Still, two sources said no one failed the questions designed to identify a media leaker.

That contrast—an expansive investigation but no apparent breakthrough—defines the episode. The White House reportedly viewed reports on depleted stocks of long-range missiles and Patriot interceptors as a serious threat, while Pentagon officials defended the inquiry as necessary to protect troops and national security. “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,” spokesman Sean Parnell said.

Defense Secretary Pete Hegseth has widened the pressure by creating a joint Pentagon–Justice Department task force, granting the Pentagon’s general counsel broad authority to demand records and responses within two days. Hegseth’s justification is stark: “Leaked information risks lives.”

Yet the investigation also carries institutional risks. Federal law and Pentagon regulations limit when polygraphs can be used and require procedural safeguards, while the tests did not include Joint Chiefs Chairman Gen. Dan Caine and reportedly did not involve the FBI. The result is a campaign that promises accountability, but so far has delivered neither a named leaker nor clear evidence that the extraordinary tactics have worked.
