Pentagon officials have subjected roughly 50 members of the Joint Staff to polygraph examinations in a bid to identify the source of recent classified leaks, according to defence sources. The investigation focuses on disclosed information pertaining to American weapons stockpile deficiencies and military preparedness concerns during operations connected to Iran.

According to reports, none of the military personnel tested failed their polygraph examinations during the initial phase of the investigation. The leaks, which revealed sensitive details about defence capabilities and supply chain vulnerabilities, prompted senior military leadership to launch a comprehensive internal probe.

The disclosure of such information raised concerns among defence officials about potential breaches of operational security and the handling of classified material within the Pentagon's highest command structures. The investigation represents a significant effort to plug information gaps within the defence establishment.

The leak inquiry underscores ongoing tensions within the Trump administration regarding media disclosures of military and defence information. Officials have expressed concern about the broader implications of such leaks for national security and military operations in the Middle East region.
