Investigation Launched into Hegseth's Use of Signal App for Military Communications
Pentagon’s inspector general examines possible policy violations in Hegseth’s messaging practices following a privacy breach.
The inspector general of the U.S. Department of Defense has officially opened an investigation into Pete Hegseth’s use of the Signal messaging application to communicate with high-ranking officials regarding military actions against Houthi rebels in Yemen. The inquiry was prompted by a notable incident where a journalist was unintentionally included in a group chat where intricate details about the military strikes were shared.
This investigation comes at the request of the Republican-controlled Senate Armed Services Committee, which expressed concerns regarding the adherence of the defense secretary and others to the established departmental policies governing the use of messaging applications for official discussions. Acting Inspector General Steven Stebbins has issued a letter to Hegseth demanding the identification of two contacts relevant to the investigation within five days—one from the government who has knowledge of the situation and a senior member of the Executive Service or a military officer.
The White House has been under scrutiny as a result of a group conversation on Signal that included Atlantic magazine’s editor-in-chief Jeffrey Goldberg, where Hegseth detailed the exact timings of military strikes and discussed weapon packages, raising numerous questions regarding operational security. In the aftermath of this breach, Democrat lawmakers have called for resignations from various officials, including Hegseth and National Security Adviser Mike Waltz, who initiated the group chat. The Trump administration maintains that the details shared were not classified information.
On March 26, Senate Armed Services Committee leaders—Republican Roger Wicker and Democrat Jack Reed—requested further examination into the messages exchanged in the Signal chat, how they relate to defense department protocols on handling sensitive data on non-government platforms, and suggestions for future actions the government may need to consider.
As the investigation unfolds, the implications of using commercial messaging tools for sensitive government discussions continue to be a pressing issue in the context of national security and operational policy.
