In March 2025, a group chat on Signal labelled “Houthi PC small group” was set up by Mike Waltz (as National Security Adviser) and included several senior administration officials such as Pete Hegseth (Defense Secretary), Tulsi Gabbard (Director of National Intelligence), John Ratcliffe (CIA Director), Vice President J.D. Vance, Secretary of State Marco Rubio and Treasury Secretary Scott Bessent. While discussing a planned U.S. military strike in Yemen against the Houthi rebels, the group chat inadvertently included Jeffrey Goldberg, editor-in-chief of The Atlantic, who was added without clearance. The chat shared detailed operational information — such as weapon types, timing and which forces would be used — on a non-government, encrypted commercial app rather than secure U.S. military communication systems.
