Pentagon gave polygraph tests to high-ranking officials to find leakers: Reports

Some of the U.S. military’s highest-ranking officials were subject to polygraph tests as part of a sweeping Pentagon investigation into leaks to journalists on dwindling weapons stockpiles amid the Iran war, multiple reports suggest.

Military officials and civilian employees were tested in August, including roughly 50 members of the Joint Staff, according to the New York Times — which first reported the investigation Friday.

Several dozen other officials, including U.S. Central Command and other combatant commands , were also tested earlier this summer, CBS News reported.

Investigators reportedly questioned officials on whether they had disclosed classified information surrounding munitions shortages , including long-range missiles and Patriot interceptors, to members of the press.

No one failed the questions, aimed to weed out anyone who may have leaked this information, two officials told CBS, adding that Joint Chiefs Chair Gen. Dan Caine was not among those tested.

President Trump was furious over the disclosures, according to CBS, which reported that only a small number of people had access to the classified information. One official said investigators were also concerned about the possibility someone with high-level access could be working with foreign intelligence.

Polygraph exams are commonly conducted on officials with access to highly classified information. Last year, the Department of Homeland Security similarly used the devices to determine the source of press leaks.

But in this case, current and former officials reportedly describe the number of senior military personnel tested in the investigation as extraordinary.

Pentagon spokesperson Sean Parnell told CBS the department “takes all leaks of classified national security information extremely seriously and investigates accordingly.”

The investigation follows months of reporting about the rate at which the U.S. has used some of its most advanced weapons since the war with Iran began on Feb. 28.

Defense Secretary Pete Hegseth has pushed back on reports of shortages, while President Trump publicly laid out his anger over leaks within the department.

“The ‘leakers’ of these treasonous statements are being hunted down,” the president wrote in an August Truth Social post. “Long term jail sentences will be sought!”
