Atlantic editor-in-chief Jeffrey Goldberg detailed how he was added to a Signal group on March 11 by Donald Trump's national security adviser Michael Walz. He wrote that he initially thought somebody was probably masquerading as Waltz trying to trap him. Two days later, Goldberg was added to a Signal chat group called 'Houthi PC small group' where JD Vance, Pete Hegseth debated on the attack on Houthis before it happened.
