The Pentagon has announced an investigation into leaks of national security information, with potential polygraph tests for Defense Department employees as part of the probes.
According to a memo from Defense Secretary Pete Hegseth’s chief of staff, Joe Kasper, the Pentagon’s intelligence and law enforcement branches are looking into recent unauthorized disclosures without revealing specific details about the leaks.
“Recent unauthorized disclosures of national security information involving sensitive communications within the Office of the Secretary of Defense (OSD) require immediate and thorough investigation,” Kasper stated.

If those responsible for the unauthorized disclosures are identified, the information will be referred for criminal prosecution,” Kasper noted.
The memo outlined that the use of polygraphs will be in line with applicable laws and policies.
President Donald Trump dismissed a report that his senior adviser, Elon Musk, would be briefed on U.S. preparations for a potential war with China, calling The New York Times “pure propaganda.”

Musk countered that those leaking false information will be prosecuted by the Pentagon. Investigations into leaks are also happening at Homeland Security and the Justice Department.
The use of polygraph tests is common in federal agencies and for national security clearances, despite not being admissible in court. The Supreme Court has also ruled against their use in military justice proceedings.
