Elon Musk and the Department of Government Efficiency (DOGE) will support the White House and National Security Council in investigating how a journalist was inadvertently added to a Signal group chat with national security officials, the White House Press Secretary confirmed on Wednesday. The inquiry follows revelations that The Atlantic’s editor-in-chief was included in a discussion involving senior cabinet members regarding a U.S. military operation in Yemen, prompting widespread concern and calls for accountability.

Addressing reporters at a press briefing, White House Press Secretary Karoline Leavitt stated that the National Security Council, the White House Counsel’s Office, and Musk’s technical team would lead the investigation. “Elon Musk has offered to put his technical experts on this to determine how this number was mistakenly added to the chat,” Leavitt said. “We are taking responsibility to ensure this never happens again.” National Security Adviser Mike Waltz accepted blame for the error, explaining that he had accidentally added Jeffrey Goldberg, editor-in-chief of The Atlantic, to the encrypted chat. However, Waltz struggled to clarify how Goldberg’s contact details appeared in his phone, asserting that he did not know him or communicate with him previously.
Former President Donald Trump suggested that Goldberg may have inserted himself into the chat, claiming the technology could allow unauthorised access. While an internal inquiry is ongoing, five senior officials involved in the Signal group chat—Vice President JD Vance, Secretary of State Marco Rubio, Secretary of Defense Pete Hegseth, Director of National Intelligence Tulsi Gabbard, and CIA Director John Ratcliffe—are now facing a federal lawsuit. The lawsuit, filed by the nonprofit American Oversight, demands that cabinet members preserve the Signal messages, arguing that the use of an encrypted, commercially available app for official discussions breaches federal regulations.

Although The Atlantic described the leaked messages as containing “war plans” and “attack plans” with classified details, the White House maintains that no sensitive information was compromised. However, messages published by the outlet on Wednesday indicate that Hegseth disclosed the exact timing of U.S. military personnel departures and the schedule for their strikes in Yemen, raising further security concerns.
