In a significant shake-up of the national security team, former National Security Advisor Mike Waltz has been nominated by President Donald Trump to serve as the next U.S. Ambassador to the United Nations. Secretary of State Marco Rubio will take over Waltz’s duties in the interim, continuing to lead the State Department while stepping into the powerful security role.
Trump made the announcement shortly after reports confirmed both Waltz and his deputy would exit their current positions. This shift comes amidst criticism surrounding Waltz's recent misstep involving a sensitive military discussion.
Mike Waltz’s Messaging Misstep Draws Fire
The move follows weeks of scrutiny over a security breach. Waltz reportedly added The Atlantic’s editor-in-chief to a private Signal chat used to coordinate a classified military operation against Houthi militants in Yemen. Although no classified data was believed to be exposed, the incident raised alarm within the administration. Critics questioned Waltz’s judgment, while others defended it as a simple error. Trump, however, maintained public support throughout.
Rubio Steps In — For Now
Rubio's interim role mirrors a historic precedent set by Henry Kissinger in the 1970s. But it's unclear how long he will juggle both duties. With global tensions high — ongoing wars in Gaza and Ukraine, rising nuclear threats from Iran, and economic instability fueled by Trump’s tariff policies — Rubio's plate is full.
Mike Waltz Responds to Nomination
Waltz expressed his gratitude following the nomination. “I’m deeply honored to continue my service to President Trump and our great nation,” he stated. However, he now faces a Senate confirmation hearing. Lawmakers, particularly Democrats, are expected to grill him on the Signal messaging blunder. Senator Chris Coons noted the upcoming hearing would be “thorough.”
Trump Scrapped Earlier Pick for UN Ambassador Role
Waltz’s nomination came after Trump pulled Rep. Elise Stefanik from consideration for the U.N. post. Concerns about maintaining Republican control in the House prompted the reversal. Waltz’s confirmation could be smoother, given his strong ties within the administration — but controversy still looms.
More Changes Could Be Coming
Trump is reportedly weighing several names for a permanent national security advisor. Contenders include special envoys Steve Witkoff and Richard Grenell, counterterrorism expert Sebastian Gorka, and senior diplomat Michael Anton.
Witkoff, known for his work in Middle East peace negotiations, has shown reluctance to take the role. He prefers his current independent position, sources say.
Grenell, meanwhile, brings broad diplomatic experience. He’s also exploring a possible run for California governor in 2026.
Loomer’s Influence and Mike Waltz’s Exit
Right-wing activist Laura Loomer had long pushed for Waltz’s removal, citing disloyalty to Trump’s “Make America Great Again” vision. After news of Waltz’s exit surfaced, Loomer claimed victory on social media, writing: “SCALP.”
Despite the backlash, experts say Trump’s decision gives Waltz a “soft landing.” Analyst Mark Montgomery believes the move avoids a public dismissal while allowing Trump to reshape his team quietly. “He tried hard to adapt,” Montgomery said. “But the pressure from Trump-world loyalists was relentless.”
Hegseth’s Role Under Investigation
Meanwhile, scrutiny has intensified around Defense Secretary Pete Hegseth. Though Waltz created the Signal group, Hegseth reportedly posted operational details, such as aircraft launch times, to the unencrypted chat. Worse, he is alleged to have shared that data with dozens of unauthorized individuals, including family members. Reports also claim he bypassed Pentagon protocols by installing an unsecured computer in his office.
An ongoing Pentagon investigation will determine whether any sensitive information was compromised. Despite criticism from both parties, Trump continues to back Hegseth publicly.
High Stakes Ahead
As Trump reshuffles key positions, the administration enters a critical phase. National security challenges are mounting. Internal loyalty tests are intensifying. And with Waltz’s confirmation and Rubio’s double duty, all eyes are now on how this new chapter unfolds.
