In a significant breach of national security protocol, top Trump administration officials shared classified military operation details in a Signal messaging app group chat that inadvertently included a journalist, according to multiple sources [1,2,3].

The Atlantic's editor-in-chief Jeffrey Goldberg reported on March 24, 2025, that he was accidentally added to a group chat titled 'Houthi PC small group' by National Security Advisor Mike Waltz. The chat included sensitive operational details about U.S. strikes on Houthi targets in Yemen that occurred on March 15 [1,6].

The National Security Council confirmed the authenticity of the message chain. 'This appears to be an authentic message chain, and we are reviewing how an inadvertent number was added to the chain,' said NSC spokesperson Brian Hughes [2].

The group chat included high-ranking officials such as Vice President JD Vance, Secretary of State Marco Rubio, Defense Secretary Pete Hegseth, Director of National Intelligence Tulsi Gabbard, and CIA Director John Ratcliffe [1,3].

Defense Secretary Hegseth shared detailed operational plans approximately two hours before the strikes, including information about targets, weapons deployment, and attack sequencing [6]. The use of Signal, a commercially available encrypted messaging app, for sharing sensitive military information raises serious security concerns as it is not an approved platform for classified communications [2,6].

The incident has drawn sharp criticism from lawmakers. 'This is one of the most stunning breaches of military intelligence I have read about in a very, very long time,' said Senate Democratic Leader Chuck Schumer [2]. Senator Jack Reed, the top Democrat on the Senate Armed Services Committee, called it 'one of the most egregious failures of operational security' [1].

President Trump, when asked about the incident, stated he was unaware of it. 'I don't know anything about it. You're telling me about it for the first time,' Trump said [1]. The White House later issued a statement expressing continued confidence in the national security team [2].

The breach is particularly notable as it comes just days after the Pentagon announced a zero-tolerance policy for leaks of sensitive information, including the potential use of polygraphs on defense personnel [6].
