Politics | 9/15/2025

The Pentagon’s internal watchdog has concluded a comprehensive review of Secretary of Defense Pete Hegseth’s utilization of the encrypted messaging app Signal for communication regarding sensitive military matters. This investigation, spanning several months, has reached its conclusion, with the watchdog now having submitted its findings to Secretary Hegseth for his perusal. The examination focused on the appropriateness and security implications of the Secretary’s choice to employ Signal for discussions related to military operations.

The use of Signal, an encrypted messaging platform known for its security features, by a high-ranking official like Secretary Hegseth raises questions about the safeguarding of classified information and adherence to communication protocols within the defense establishment. This review by the Pentagon watchdog underscores the significance of ensuring that official communications involving sensitive national security issues are conducted in a secure and authorized manner.

While the specific details of the watchdog’s findings and recommendations to Secretary Hegseth have not been disclosed publicly, the completion of this review signals a critical juncture for the Department of Defense in upholding transparency and accountability in its internal communications practices. The implications of this assessment may prompt adjustments in protocols or guidelines related to the use of encrypted messaging apps within the Pentagon’s communication framework.

In response to inquiries about the review’s outcome, a spokesperson for the Department of Defense declined to comment on the specifics, citing the confidential nature of internal investigations. It remains to be seen how Secretary Hegseth will address any potential recommendations stemming from the watchdog’s assessment of his use of Signal for discussing sensitive military operations. As the Pentagon continues to prioritize security and compliance with communication protocols, the completion of this review marks a pivotal moment in the department’s ongoing efforts to uphold the integrity of its internal communications processes.
