National Security Advisor Michael Waltz and a senior aide used personal Gmail accounts for government communications, according to a Washington Post report published yesterday.

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.

According to three officials who spoke to the Washington Post, members of President Trump's National Security Council, including Waltz, have conducted government business over personal Gmail accounts.
