Watlz corresponded with government officials via Gmail, less secure way to communicate than Signal - Washington Post

US National Security Advisor Mike Waltz and his subordinates used personal Gmail accounts during government correspondence.
According to the Washington Post, this information stems from the leak of classified data to a journalist via the Signal messenger, Censor.NET reports citing Hromadske.
Journalists point out that Gmail is a much less secure way of communication than the aforementioned Signal. American officials told the publication that Volz sent less confidential but "potentially usable" information, such as his schedule and other work documents, by mail.
According to the Washington Post, the use of personal email, even for unclassified material, is risky given that foreign intelligence agencies highly value the communication and scheduling of senior government officials.
However, Watlz's spokesman, Brian Hughes, said he had seen no evidence that the US national security adviser had used his personal email for matters related to his position.
When asked whether Watlz discussed sensitive military matters via Gmail, Hughes said that Trump administration staffers are instructed to use "only secure platforms for classified information."
Leak of confidential information from Signal chat
Earlier, the editor-in-chief of The Atlantic, Jeffrey Goldberg, accidentally joined a private chat on Signal where members of the US presidential administration discussed strikes on Yemen.
Trump also said that he was "unaware" of the report by The Atlantic journalist, who was accidentally added to a secret Signal chat where members of his administration discussed strikes on Yemen.
Subsequently, US Secretary of Defense Pete Hagel denied that US military plans were discussed in the chat room and accused The Atlantic's editor-in-chief of "spreading fake news."
Later, the White House, commenting on the Signal scandal, said that the case was closed and that Trump retained confidence in Volz.
