Overview

• Defense Secretary Pete Hegseth shared operational details, including timing and weaponry, in the chat, which were later published by The Atlantic.
• The Trump administration denies that classified information was shared, despite screenshots showing sensitive details, and President Trump has defended Waltz and downplayed the incident.
• The Pentagon has issued guidance discouraging the use of Signal for sensitive communications, citing security vulnerabilities and risks to operational security.
• Lawmakers from both parties have criticized the breach, with some calling for the resignations of Waltz and Hegseth over the mishandling of sensitive information.
