The Atlantic published a follow-up report releasing the entire Signal chat among Trump's senior national security officials detailing the Yemen attack, including F-18 launch and drone strikes. US National Security Advisor Michael Walz accepted responsibility for the group chat. White House Press Secretary Caroline Leavitt called the report a hoax, while Vice President J.D. Vance said Atlantic editor-in-chief Jeffrey Goldberg oversold it. Senate members have called for resignation of top security officials.
