A Pentagon examination has revealed potential security breaches involving U.S. Defense Secretary Pete Hegseth and the discussion of sensitive military operations via the encrypted messaging app Signal. The inquiry, focused on planning related to strikes against Houthi rebels in Yemen, raises concerns about adherence to security protocols within the administration and follows the earlier removal of former National Security Advisor Mike Waltz from his position after an unauthorized journalist gained access to the same communication channel [[1]]. While a spokesperson for Secretary Hegseth has dismissed the findings, the allegations add to ongoing scrutiny of the Pentagon’s conduct of military actions in multiple global hotspots.
U.S. Defense Secretary Pete Hegseth may have compromised military operations by discussing planned strikes in Yemen via the encrypted messaging app Signal, according to a recent internal investigation by an independent body within the Pentagon. The findings raise questions about security protocols within the Trump administration as it navigates multiple international conflicts.

The U.S. military launched a campaign earlier in 2025 targeting Houthi rebels, citing the need to protect freedom of navigation and international commerce through the Red Sea. The investigation centers on a Signal group chat discussing these operations.
Former National Security Advisor to Donald Trump, Mike Waltz, was removed from his position in early May after a journalist from The Atlantic was inadvertently added to the Signal discussion group.
This latest inquiry determined that Secretary Hegseth, who was also part of the Signal group, potentially endangered military personnel through his participation. The development underscores the risks associated with using unsecure communication channels for sensitive military planning.
Messages within the group reportedly revealed the timing of planned strikes hours before they were executed, as well as details regarding the military equipment to be used.
However, a spokesperson for Secretary Hegseth dismissed the findings, stating on X, “This is a TOTAL exoneration of the Secretary.” The spokesperson, Sean Parnell, added, “It demonstrates what we’ve known all along: no classified secret information was shared,” and declared, “This case is closed.”
The controversy surrounding Hegseth comes as the Pentagon faces scrutiny over military operations in the Pacific and Caribbean, purportedly aimed at combating drug trafficking. Critics have questioned the legality of these strikes, citing a lack of evidence linking targeted vessels to drug cartels.
Specifically, an operation involving a second strike on a previously damaged vessel, resulting in the deaths of survivors, has drawn significant criticism. To date, more than 80 people have been killed in these military campaigns.
U.S. strikes in Yemen concluded in May following an agreement reached between the United States and Houthi rebels.
The Houthis had previously launched several attacks in the Red Sea against ships they claimed were connected to Israel or its allies, stating their actions were in support of Palestinians in Gaza following the October 7, 2023, Hamas attack.
