The Pentagon subjects 50 of its top leaders to lie detector tests.

U.S. officials revealed that approximately 50 senior officers and staff members of the Joint Chiefs of Staff in the U.S. Army underwent polygraph tests last month.

This was part of a broader investigation to determine the source of sensitive media leaks regarding the nation's stockpiles of advanced munitions amid the war with Iran.

The investigators' questions focused on whether the mentioned officials had leaked confidential information to the media, particularly concerning the acute shortage of long-range missiles and Patriot interceptor missiles.

Three sources who spoke to CBS News indicated that President Donald Trump was angry about these leaks, given the limited number of individuals authorized to access those details, raising security concerns over the possibility of a foreign intelligence agent among them.

Although polygraph tests are considered part of the routine procedures for renewing security clearances for senior officials, the number and scope of these tests reaching the highest military levels has been described as "unprecedented" in recent history.

The New York Times reported retired Admiral Donald Guter stating, "I have never seen polygraph testing used on such a scale or at this high level of military rank."

Two informed sources reported that none of the officials who underwent the test failed the questions designed to determine if they were the source of the media leaks. The investigation is taking place in an atmosphere of distrust and suspicion within the Department of Defense, amid criticism of Secretary of Defense Pete Hegseth, who some sources have accused of fostering this atmosphere and surrounding himself with a tight circle of loyalists. Reports indicate that Hegseth has fired or obstructed the promotions of at least 80 generals, admirals, and other officials since the beginning of last year.

For his part, Pentagon spokesperson Shawn Barnell stated in a statement to CBS News: "The department does not comment on internal matters related to individuals or investigations, but it takes all leaks of classified national security information very seriously and investigates them accordingly. Securing classified information is critical to ensuring the safety of the United States and our forces deployed around the world."
