National Security Adviser Michael Waltz is under scrutiny for using his personal Gmail account to discuss government matters, including military positions and weapons systems. The revelations follow an earlier controversy in which he inadvertently invited a journalist to a Signal chat about a planned military strike. While Waltz denies sending classified information via unsecured channels, concerns over cybersecurity risks and record-keeping compliance continue to mount. The White House has defended Waltz, but criticism from political figures remains strong.
