Defense Department Investigation Concludes Defense Secretary Put Military Personnel in Danger with Messaging App Chat.

A highly anticipated Department of Defense review has concluded that Defense Secretary Pete Hegseth breached departmental policies by disclosing classified information in a Signal messaging chat, as stated by a person briefed on the findings.

Details of the Incident

The online conversation in dispute included details about a planned airstrike in Yemen targeting Houthi militants. This discussion was revealed after a reporter for the Atlantic was added as a participant.

Other officials in the group reportedly included JD Vance, CIA director John Ratcliffe, and former security advisor Mike Waltz. The report did not examine the conduct of Hegseth, as the other participants do not work at the Pentagon.

Signal is a commercially offered communication application that was not approved for handling classified information.

Serious Risk to Forces

The inspector general's report determined that the information circulated by Hegseth was secret and could have endangered the safety of US troops if it had been intercepted by a foreign enemy force.

Notably, the report also noted that Hegseth possessed the authority to declassify the material he shared, though it was unclear whether he formally exercised that authority.

Secretary's Response

The informed individual said that Hegseth refused to be interviewed by the investigators. Instead, he provided a brief written statement.

In his statement, Hegseth asserted he only disclosed details that would not have risked lives or compromised the mission. He further stated that he had the right to downgrade information and viewed the inspector general to be partisan.

Future Actions

The completed report has been provided to lawmakers. An unclassified version is expected to be made public in the coming days.
