Overview

• The investigation will assess compliance with Department of Defense policies, including those on classification standards and federal records retention requirements.
• The Signal group chat, created by National Security Advisor Mike Waltz, inadvertently included journalist Jeffrey Goldberg, who later published operational details of the Yemen airstrikes.
• Bipartisan leaders of the Senate Armed Services Committee requested the investigation, citing concerns about the use of unclassified networks to discuss sensitive military information.
• President Trump has defended Hegseth and Waltz, stating no classified information was shared and no personnel will face termination over the incident.
