Members of President Donald Trump’s National Security Council, including White House national security adviser Michael Waltz, have conducted government business over personal Gmail accounts, according to documents reviewed by The Washington Post and interviews with three U.S. officials.
The use of Gmail, a far less secure method of communication than the encrypted messaging app Signal, is the latest example of questionable data security practices by top national security officials already under fire for the mistaken inclusion of a journalist in a group chat about high-level planning for military operations in Yemen.
A senior Waltz aide used the commercial email service for highly technical conversations with colleagues at other government agencies involving sensitive military positions and powerful weapons systems relating to an ongoing conflict, according to emails reviewed by The Post. While the NSC official used his Gmail account, his interagency colleagues used government-issued accounts, headers from the email correspondence show.
Waltz has had less sensitive, but potentially exploitable information sent to his Gmail, such as his schedule and other work documents, said officials, who, like others, spoke on the condition of anonymity to describe what they viewed as problematic handling of information. The officials said Waltz would sometimes copy and paste from his schedule into Signal to coordinate meetings and discussions.
