The Pentagon polygraphs about fifty Joint Staff members in a hunt for who spoke to reporters
The Department of Defense administered polygraph examinations to military officers and civilian employees in August 2026, including roughly 50 members of the Joint Staff, as part of an investigation into disclosures to the press about US weapons stockpiles during the war with Iran; several dozen further officials, among them US Central Command and other combatant-command personnel, were examined earlier in the summer. The reporting dates the examinations only to those months, so this row carries the date of its cited report, 5 September 2026, as a stated stand-in.
What happened
The examinations were first reported by The New York Times on Friday 4 September 2026, which carried the August timing and the figure of roughly 50 Joint Staff members; CBS News reported the earlier-summer round. Investigators asked officials whether they had disclosed classified information about munitions shortages, including long-range missiles and Patriot interceptors, to members of the press. Two officials told CBS News that no one failed the questions meant to identify a leaker, and that Joint Chiefs Chairman Gen. Dan Caine was not among those examined. In July 2026 Defense Secretary Pete Hegseth announced that the Pentagon and the Justice Department had formed a joint task force to identify and prosecute people suspected of leaking sensitive government information to the press. Pentagon spokesman Sean Parnell told CBS News that 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." President Trump wrote in an August Truth Social post that the leakers of these treasonous statements were being hunted down, adding that long term jail sentences would be sought.
Why it matters
A polygraph put to the question of who spoke to a reporter is an instrument turned inward on the department's own officers, and under Pentagon rules it is formally consensual: CBS News reports that federal law and Pentagon regulations require the person being examined to consent to or request the test. Standing up a joint task force with the department that brings criminal cases attaches a prosecution route to whatever an examination produces, so the mechanism reaches past the people actually examined to everyone who now knows the examination is available. What the record establishes is the instrument and its scale, not a consequence to any examinee — two officials told CBS News that no one failed the questions meant to identify a leaker.
