A Pentagon inspector general report has revealed that Defense Secretary Pete Hegseth potentially compromised military operational security by utilizing an unsecured commercial messaging application to discuss sensitive details of a planned airstrike in Yemen. The investigation, initiated by the Republican-led Senate Armed Services Committee, determined that Hegseth violated established Department of Defense policy by transmitting classified information via his personal device on the Signal app.
The security breach gained public attention when an Atlantic magazine editor was inadvertently added to the group chat by then-National Security Adviser Mike Waltz. The exposed communications included specific operational details such as target coordinates, mission timing, and weapon specifications—information derived from a classified email marked ‘SECRET//NOFORN,’ indicating its potential to damage national security if disclosed to foreign entities.
While the inspector general confirmed that Hegseth shared materials from a classified report, the investigation could not ascertain whether the defense secretary had formally exercised his authority to declassify the information prior to its dissemination. The classified version of the report was delivered to Congress on Tuesday, with an unclassified version anticipated for public release later this week.
The Pentagon has vigorously defended Hegseth, with a spokesperson characterizing the report as ‘a total exoneration’ that confirms ‘no classified information was shared.’ White House Press Secretary Karoline Leavitt similarly asserted that ‘no classified information was leaked, and operational security was not compromised.’
However, Senator Mark Warner, the Democratic vice chair of the Senate Intelligence Committee, has called for Hegseth’s resignation, stating the report demonstrates ‘a broader pattern of recklessness and poor judgement.’ Warner emphasized that the findings leave ‘no doubt: Secretary Hegseth endangered the lives of American pilots’ through his actions.
The controversy compounds existing scrutiny surrounding Hegseth’s leadership, including recent questions about his oversight of a separate military operation against suspected drug traffickers.
