Trump Ousts Waltz as National Security Advisor, Nominates Him for UN

President Donald Trump has removed National Security Advisor Mike Waltz following controversy over a leaked Signal chat that inadvertently included a journalist and exposed details of pending U.S. military operations in Yemen. Waltz, who has faced criticism for using an unclassified messaging platform for sensitive discussions, will instead be nominated as the next U.S. Ambassador to the United Nations. Secretary of State Marco Rubio will serve as interim National Security Advisor while also retaining his current position, marking the first time since the 1970s that one individual holds both roles simultaneously. The White House initially expressed support for Waltz, calling the incident a mistake, but ultimately decided a leadership change was needed after the security breach fueled public and expert concerns. This marks the first major shakeup in Trump's second term and underscores ongoing scrutiny over handling of classified information within the administration. Trump praised both Waltz’s service and Rubio’s ability to address critical national security issues.
