Breaking: Trump Names Mike Waltz U.N. Ambassador; Rubio to Serve as Interim National Security Adviser

mai 01, 2025

President Donald Trump announced in a social media post on Thursday that National Security Adviser Mike Waltz will leave his current post to serve instead as U.S. ambassador to the U.N., pending Senate confirmation. The president said that Secretary of State Marco Rubio will serve as acting national security adviser in the meantime.

"From his time in uniform on the battlefield, in Congress and, as my National Security Advisor, Mike Waltz has worked hard to put our Nation's Interests first. I know he will do the same in his new role," Trump wrote on Truth Social.

Waltz’s removal as national security adviser, first reported by Mark Halperin of 2Way, comes weeks after the former Florida congressman inadvertently added a journalist to a private Signal chat in which administration officials discussed sensitive information surrounding a U.S. military strike on Houthi rebels. President Donald Trump defended Waltz after the Atlantic’s report, telling reporters he “learned a lesson, and he's a good man.” But behind the scenes, administration officials grew frustrated with his team’s handling of the Signal news cycle.

Intra-White House tensions surrounding his team’s administrative competence were compounded by ideological differences in the administration that preceded the Signal chat debacle. According to sources familiar with the matter, some White House officials grew concerned that Waltz’s hawkish instincts regarding Iran and Russia put him at odds with the more restraint-minded foreign policy leanings of others in the administration who view China as the biggest threat to national security.

Waltz’s ouster from his NSA post is a major shakeup in the president’s national security team as the administration confronts major challenges on the world stage, including the continuing war between Israel and Hamas and Russia’s ongoing invasion in Ukraine. The Trump administration has also spent recent weeks trying to broker talks with Iran regarding Tehran’s nuclear program.

Waltz is Trump’s second pick to serve as U.S. ambassador to the U.N. Trump’s first choice, Representative Elise Stefanik (R., N.Y.), was pulled from consideration amid concerns surrounding the House GOP’s slim majority, though her withdrawal preceded the confirmation process.

The White House did not immediately respond to a request for comment.
