Senior members of the Trump administration’s National Security Council, including national security advisor Michael Waltz, used personal Gmail accounts for government work.
Sensitive military positions and powerful weapons system discussions were conducted on a consumer version of Gmail, which is not approved for government use.
Waltz received less sensitive but potentially exploitable information on his personal Gmail account, such as schedules and work documents.
The use of personal Gmail accounts for government communication is considered problematic due to the risk of phishing attacks and information security breaches.
