On 11 March 2025, National Security Advisor Mike Waltz accidentally added The Atlantic editor Jeffrey Goldberg to a Signal group chat called 'Houthi PC small group' that included Defense Secretary Pete Hegseth, VP JD Vance, Secretary of State Marco Rubio, DNI Tulsi Gabbard, senior adviser Stephen Miller, envoy Steve Witkoff, and others. The group discussed and coordinated US military strikes on Yemen. Goldberg published his account on 24 March 2025 with some details redacted; Hegseth had shared specific weapons and strike timings approximately two hours before attacks occurred. Congressional hearings followed. Waltz was subsequently reassigned to serve as US Ambassador to the United Nations.
