Mike Waltz defends his use of Signal app during Senate hearing
Mike Waltz takes ‘full responsibility’ for leaked Trump administration Signal chat about Yemen strike
National security adviser Mike Waltz faced questioning regarding his use of the encrypted app Signal for sensitive military discussions, a matter dubbed the “Signalgate” scandal.
During a Senate hearing, Waltz was questioned about adding The Atlantic editor Jeffrey Goldberg to a Signal group chat discussing a military operation in Yemen.
Waltz defended his actions by asserting that the use of Signal was authorized under Biden-era Cybersecurity and Infrastructure Security Agency (CISA) guidance.
Conversely, Department of Defense policy explicitly prohibited the use of commercial encrypted messaging applications, including Signal, for transmitting non-public DoD information.
Despite the controversy, Waltz and other officials involved maintained that no classified information was exchanged within the Signal group chat.
