Pentagon Investigation Concludes Defense Secretary Put Troops in Jeopardy with Messaging App Conversation.

A long-awaited Pentagon report has concluded that Defense Secretary Pete Hegseth breached official protocols by sharing classified intelligence in a private Signal group, according to a person briefed on the findings.

Details of the Event

The chat group in dispute contained details about a scheduled air attack in Yemen against Houthi militants. This discussion came to light after a journalist for the Atlantic was included as a participant.

Other officials in the chat reportedly included Senator JD Vance, CIA director John Ratcliffe, and then-national security adviser Mike Waltz. The investigation did not examine the conduct of Hegseth, as the other participants are not employed at the Pentagon.

Signal is a commercially offered messaging app that was not authorized for transmitting classified information.

Potential Risk to Forces

The internal investigation determined that the intelligence shared by Hegseth was classified and posed a risk to the safety of US service members if it had been intercepted by a foreign enemy force.

Notably, the document acknowledged that Hegseth had the ability to downgrade the information he shared, though it was not specified whether he actually exercised that authority.

Secretary's Response

The source said that Hegseth refused to be interviewed by the investigators. Instead, he submitted a brief written statement.

In his statement, Hegseth claimed he only disclosed information that would not have endangered personnel or compromised the mission. He further stated that he had the right to declassify material and viewed the inspector general to be partisan.

Next Steps

The finalized investigation has been shared with lawmakers. An publicly releasable copy is anticipated to be released later this week.
