Earlier this week, the Wall Street Journal reported that Waltz had “created and hosted multiple other sensitive national-security conversations on Signal with cabinet members,” including chats centered around brokering a lasting peace deal between Russia and Ukraine.

It’s a more extensive use of the app than previously reported and sheds new light on how commonly the Trump administration’s national security team relies on Signal.

The Atlantic's editor-in-chief Jeffrey Goldberg reported he was accidentally added by Mike Waltz to a group chat containing secret military plans.

U.S. President Donald Trump's national security adviser has never used his personal email account to send classified material, the White House said, following a report that Mike Waltz and other National Security Council members used Gmail for government work.

Trump’s National Security Adviser was using Gmail for sensitive discussions—which is far less secure than Signal.

The National Security Council (NSC) has provided clarification on reports about Mike Waltz and his staff using personal Gmail accounts for government communications.
