Defense Department Investigation Finds Defense Secretary Placed Troops in Jeopardy with Messaging App Chat.

A highly anticipated Department of Defense report has determined that Pentagon chief Pete Hegseth violated official protocols by disclosing secret information in a Signal messaging chat, according to a person briefed on the findings.

Details of the Incident

The chat group in dispute contained particulars about a planned airstrike in Yemen against Houthi militants. This chat came to light after a reporter for the Atlantic was included as a member.

Other officials in the chat allegedly included JD Vance, CIA director John Ratcliffe, and then-national security adviser Mike Waltz. The investigation focused solely on the conduct of Hegseth, as the other officials do not work at the Department of Defense.

Signal is a commercially offered messaging app that was not approved for handling sensitive material.

Potential Threat to Troops

The inspector general's report found that the information circulated by Hegseth was classified and posed a risk to the lives of US troops if it had been intercepted by a hostile nation.

Notably, the document acknowledged that Hegseth possessed the authority to downgrade the material he shared, though it was unclear whether he actually exercised that authority.

Hegseth's Response

The informed individual said that Hegseth declined an interview by the investigators. Instead, he provided a short written response.

In his response, Hegseth asserted he only disclosed information that would not have risked lives or compromised the operation. He further stated that he possessed the authority to downgrade information and viewed the inspector general to be partisan.

Next Steps

The finalized investigation has been provided to Congress. An unclassified version is expected to be made public in the coming days.
