Overview

• National Security Adviser Mike Waltz's team reportedly used at least 20 Signal group chats to discuss sensitive issues across regions like Ukraine, China, Gaza, and the Middle East.
• Sources revealed that sensitive, though not classified, information was frequently shared in these chats, raising concerns about security vulnerabilities and compliance with federal record-keeping laws.
• The Pentagon previously warned against using Signal for sensitive communications, citing risks of foreign hacking through the app's 'linked devices' feature.
• Reports also indicate Waltz's team used personal Gmail accounts for government business, further compounding security and transparency concerns.
• Despite bipartisan criticism and calls for Waltz's resignation, the White House has defended his actions and declared the investigation into the Yemen Signal chat incident closed.
