Trump replaces Mike Waltz as NSA, nominates him UN ambassador

President Donald Trump announced a significant reshuffle of his national security team, removing Mike Waltz as national security adviser and nominating him to be the next U.S. ambassador to the United Nations. Secretary of State Marco Rubio will serve as interim national security adviser while continuing his current duties. Waltz's departure follows the 'Signalgate' scandal, where he inadvertently added a journalist to a sensitive group chat discussing military plans, resulting in heightened scrutiny and expected tough questioning during his Senate confirmation. Trump praised Waltz's service in both Congress and the administration, expressing confidence in his new role at the U.N. This marks one of the first major changes in Trump's inner circle since taking office and reflects ongoing efforts to address internal controversies while maintaining leadership continuity.
