Trump replaces Mike Waltz as national security adviser with Marco Rubio | Donald Trump News

U.S. President Donald Trump announced his plan to reassign Mike Waltz, remove him from his current position as national security adviser and nominate him as UN ambassador.

Thursday’s revelation came on a strongly speculative morning when Waltz and his second order, Deputy National Security Adviser Alex Wong was kicked out of their role.

“I am pleased to announce that I will nominate Mike Waltz as the next U.S. ambassador,” Trump wrote in his social media platform Truth Social. “Mike Waltz strives to put the interests of our country first. I know he will do the same in his new position.”

Trump said Secretary of State Marco Rubio will continue to serve as national security adviser while continuing to serve as the country's top diplomat.

“Together, we will continue to work tirelessly to make the United States and the world safer again,” Trump said.

The president's message appears to confirm the reorganization of the first major personnel in his second term. Earlier in the day, anonymous sources told major U.S. news outlets that Waltz was forced to be forced after relations with Trump cooled.

Waltz's reputation has been plagued by an incident in which he appears to have added a reporter to a private chat on the app signal, which shares details of the U.S. military attack.

But Trump has publicly represented by Waltz and refused to punish the signal scandal.

During his first term, Trump also developed the habit of riding a bicycle through a national security adviser. During his four years in office, he has four different national security advisers, Starting with retired Lieutenant Michael Flynn, who lasted only four weeks.

Waltz was a former U.S. Congressman and has represented Florida's Sixth District since 2019. Although he was reelected in 2024, he resigned from Congress in January to join the Trump administration.

Previously, he served as the green beret for the special forces in the U.S. Army.

“Mike has been a strong champion of my first foreign policy agenda in the United States and will be a huge advocate of our pursuit of peace through strength,” Trump wrote on November 12.

But Waltz's foreign policy background has been the source of censorship. Although Trump has positioned himself as a “peacemaker” in his second term, he promised to end the world conflict, critics point out that Waltz has taken a more hawkish stance in history.

He served as a counterterrorism adviser for former President George W Bush's administration, Dick Cheney, who opposed a massive withdrawal from Afghanistan without a Taliban concession.

This makes Waltz and his staff the target of Trump’s “Make America Great Again” (MAGA) base. At a White House meeting in April, far-right social media figure Laura Loomer reportedly criticized national security officials, including waltz.

After that meeting, Trump fired six National Security Council (NSC) officials, although Waltz and Huang were not among them.

On Thursday, Loomer appeared to celebrate Waltz and Wong's departure on social media. “I hope the rest will be fired, but the NSC is promoted under Waltz,” she wrote.

But Waltz's position in the White House was particularly weakened after the revelation of the Revelation, which was added to a private chat in Atlantic magazine editor Jeffrey Goldberg, in which senior officials discussed the bombing movement in Yemen.

Goldberg said in the Chronicle of the incident that he received an unexpected invitation to a signal account known as Waltz. At first, Goldberg questioned whether the invitation was true. But after accepting, he found himself in conversation with individuals including Defense Secretary Pete Hegseth, Vice President Judd Vance and Secretary of State Rubio.

They appear to be discussing upcoming plans to bomb targets related to Yemen's armed group Houthis. These details shared by Hegseth include the precise timing and aircraft used in the bombing activities.

Waltz acknowledged his role in the scandal, and the White House has since said the issue was “closed”.

“I take full responsibility. I set up a group,” Walz told Fox News in March. He added in Goldberg: “We have the best technical thinking and have studied how this happens. But I can tell you 100%: I don't know this person.”

To take on the new role of the UN ambassador, Waltz will face a Senate confirmation hearing, a process that does not have to serve as a national security adviser. His involvement in the “signal gate” scandal could play a central role in the Senate inquiry.

The UN ambassador's position has been open since Trump nominated for representative Elise Stefanik on March 27 because her seat in Congress is too valuable (too fragile) to snap up in the 2026 midterm elections.

Waltz admitted in a line of social media post Thursday that he nominated his nomination.

“I am honored to continue to serve President Trump and our great nation,” he wrote.
