Signal Groups Took Over National Security Comms

National Security Adviser Mike Waltz and his staff created more than 20 Signal groups to handle global crisis coordination. These encrypted chats covered hotspots like Gaza, Ukraine, China, and Africa. Several participants said these Signal groups became the go-to platform for urgent discussions, often including high-ranking officials.

This level of Signal use goes beyond what was previously known. It now appears central to how the Trump administration’s NSC communicates in real time.

Experts Warn Of Signal Group Risks

Former intelligence officials say these Signal groups may have exposed sensitive material to risk. The app’s disappearing message function raises concerns about compliance with federal recordkeeping laws. While Signal is allowed on some government devices, officials must preserve important messages manually.

An NSC spokesperson confirmed Signal is authorized for unclassified material. However, critics remain skeptical due to how heavily Waltz’s team relied on it.

Yemen Leak Sparks New Scrutiny

The controversy intensified after Waltz accidentally included a journalist in a Signal group about military strikes in Yemen. The chat included Defense Secretary Pete Hegseth and revealed detailed attack sequences. Many believe those details should have remained classified.

Though the White House downplayed the leak, lawmakers and security analysts called it a major breach. Some are now questioning whether this was an isolated incident or part of a broader pattern.

Congress Investigates NSC Signal Groups

Democratic members of the House Oversight Committee are demanding answers. Rep. Gerry Connolly sent letters to several group members requesting interviews. He called the situation “deeply alarming” and warned that Signal groups could violate national security norms.

Lawmakers want to know whether any classified data was shared. They also want to determine if officials kept proper records of critical discussions.

Gmail Use Raises More Red Flags

Reports have also surfaced that Waltz and some staff used personal Gmail accounts for official work. The NSC claimed this helped preserve emails for records. But critics argue the move creates more opacity in national security operations.

Sources say the team never adapted to government protocols. They continued using campaign-style communication methods well after the inauguration.

Signal Groups Replaced Formal Systems

Waltz reportedly began relying on Signal during the transition period. That reliance continued even after he took office. Multiple insiders said the app became the NSC’s default platform for almost everything.

“This wasn’t occasional use — it was how they ran things,” one former official said.

Now, that approach faces legal and political consequences. The investigation into these Signal groups may reshape how future administrations handle digital communication at the highest levels of national security.
