Former Transportation Secretary Pete Buttigieg was stunned by the revelations from The Atlantic’s editor-in-chief Jeffrey Goldberg, who reported on Monday that he was accidentally added to a group chat with some of the Trump administration’s top national security officials, in which they discussed war plans that were likely classified. Using an expletive to express his fury over the report, Buttigieg wrote in a post on X: “From an operational security perspective, this is the highest level of f---up imaginable.” The 43-year-old Navy veteran added: “These people cannot keep America safe.” In his report, Goldberg described how he was apparently added to a group chat on Signal by national security adviser Mike Waltz. Also included were Vice President JD Vance, Defense Secretary Pete Hegseth, Secretary of State Marco Rubio, Director of National Intelligence Tulsi Gabbard, and CIA Director John Ratcliffe. The members were seemingly unaware of Goldberg’s presence in the text group as they discussed strikes against the Houthi militant group in Yemen. A White House National Security Council spokesperson said Monday the messages appeared to be “authentic.”
