Trump Boots National Security Adviser Mike Waltz Over Signalgate

Introduction
President Donald Trump is set to remove National Security Adviser Mike Waltz, following weeks of mounting controversy over Waltz’s mishandling of sensitive information in an unsecured Signal group chat. The incident, which involved the inadvertent inclusion of a journalist in a discussion of classified military operations, has rocked the National Security Council (NSC) and triggered a broader purge of senior staff. Waltz’s ouster marks the first high-profile departure of Trump’s second term and underscores the administration’s heightened sensitivity to leaks, operational discipline, and internal loyalty as it navigates a turbulent national security environment.
