Trump Appoints Mike Waltz as U.N. Ambassador Following Ouster from National Security Council

In a significant move, President Donald Trump has nominated Mike Waltz, the former national security advisor, to serve as the United States Ambassador to the United Nations. This announcement comes shortly after his abrupt removal from the National Security Council earlier in the day.

Trump took to Truth Social to express his satisfaction with the nomination. He stated, “I am pleased to announce that I will be nominating Mike Waltz to be the next United States Ambassador to the United Nations.” The president highlighted Waltz’s extensive experience, mentioning his military service, tenure in Congress, and role as National Security Advisor. Trump emphasized that Waltz’s commitment to putting the nation’s interests first would continue in his new role.

Interim National Security Advisor

In his announcement, Trump indicated that Secretary of State Marco Rubio would act as the interim National Security Advisor while maintaining his leadership position at the State Department. Trump declared, “Together, we will continue to fight tirelessly to Make America, and the World, SAFE AGAIN.” This proclamation reflects Trump’s ongoing dedication to national and global security.

Waltz’s Response

Shortly after Trump’s tweet, Waltz expressed his gratitude on social media, stating he was “deeply honored to continue my service to President Trump and our great nation.” His swift response demonstrates his commitment to the administration amidst significant leadership changes.

Notable Executive Exits

The ousting of Waltz and other National Security Council staff marked a substantial turnover in the Trump administration. Emerging reports suggest that Waltz’s nomination to the U.N. occurred just hours after the news of his dismissal surfaced. This timing underscores the rapid developments in the administration’s personnel decisions.

Signal Chat Leak Controversy

Waltz’s recent departure from his post is reportedly linked to a high-profile controversy involving a leaked Signal chat. In March, the editor-in-chief of the Atlantic was mistakenly added to a group chat featuring pivotal Trump officials, including Waltz, Secretary of Defense Pete Hegseth, and CIA Director John Ratcliffe. Discussions during this chat included sensitive topics such as military actions against Houthi rebels in Yemen.

Although speculation about Waltz’s ousting had been brewing, the Trump administration asserted that no classified material was shared within the chat, and the president purportedly retained confidence in his National Security Council team.

Previous Nomination for U.N. Ambassador

Prior to Trump’s recent announcement, several names had surfaced as potential candidates for the U.N. ambassador role after Representative Elise Stefanik of New York withdrew her nomination last month. Other contenders included David Friedman, the former U.S. ambassador to Israel, Ellie Cohanim, a former deputy special envoy, and special presidential envoy Richard Grenell. Grenell distinctly stated he was not interested in the position, closing the door ahead of Trump’s announcement.

Impact of House Elections

Trump’s original choice for the U.N. ambassador position, Stefanik, had initially been announced in November 2024, shortly after his electoral victory against former Vice President Kamala Harris. However, the impending special House elections created apprehension in Trump’s circle regarding the Republican party’s thin majority in the House. Stefanik’s decision to withdraw stemmed from her awareness of the political stakes involved during this critical period.

In an interview with Fox News, Stefanik explained her rationale, emphasizing the pressure from both New York corruption issues and the importance of her presence in Congress to support Republican efforts against perceived Democratic misconduct.

Trump’s Message on Stefanik’s Withdrawal

After Stefanik’s withdrawal, Trump underscored her significance to Republican strategies, stating he favored her remaining in Congress to ensure stability within the party. Trump expressed confidence in her ability to help maintain a Republican majority during upcoming elections. He added, “There are others that can do a good job at the United Nations,” indicating his belief in a depth of talent among his nominees.

Past U.N. Leadership

Under Trump’s first term, Nikki Haley and Kelly Craft served as ambassadors to the United Nations, contributing to controversial shifts in U.S. policy towards international organizations.

Trump’s View on the U.N.

Upon taking office, Trump reduced U.S. involvement with various U.N. programs, including a withdrawal from the U.N. Human Rights Council and an end to funding for a relief agency focused on Gaza. His prior statements indicate a critical stance toward the U.N., asserting that the organization harbors untapped potential but has failed to execute its mission effectively.

As the administration navigates this new chapter, it remains to be seen how Waltz’s nomination will shape U.S. policies at the United Nations.
