WASHINGTON – In a striking move that signals a new chapter in his second term, U.S. President Donald Trump on Thursday fired National Security Adviser Mike Waltz and temporarily appointed Secretary of State Marco Rubio to the post, an extraordinary decision that consolidates two of the most powerful foreign policy roles under a single figure.
The dismissal of Waltz marks the first major personnel shakeup in Trump’s inner circle since his return to the White House in January and underscores the president’s preference for loyalty and swift decision-making.
In a social media post announcing the change, Trump praised Waltz’s contributions to national security and revealed plans to nominate him as the next U.S. Ambassador to the United Nations.
“Mike has worked hard for the good of our country,” Trump wrote. “He’ll now represent us on the global stage at the UN, where his experience will serve us well.”
However, sources close to the administration confirmed that the decision to remove Waltz had been made earlier in the day, following weeks of internal scrutiny. The 51-year-old former Florida congressman reportedly drew criticism from senior White House aides after a private, encrypted group chat on Signal involving several high-ranking national security officials came to light in March. While the contents remain undisclosed, the episode sparked unease within Trump’s national security team and may have accelerated Waltz’s exit.
The president’s move to elevate Rubio, even temporarily, is unprecedented in the modern era. Not since the days of Henry Kissinger in the 1970s has one person simultaneously held the roles of Secretary of State and National Security Adviser. The dual appointment places Rubio at the strategic center of U.S. foreign policy at a time of growing global instability and shifting alliances.
Rubio, a seasoned political figure with strong credentials in foreign affairs and a longtime Trump ally, is expected to maintain the administration’s hawkish posture on China, Iran, and border security while also advancing Trump’s doctrine of “America First” diplomacy.
The shakeup comes amid a broader effort by Trump to streamline decision-making and assert greater control over national security priorities as the 2026 midterm elections draw closer. The White House has yet to announce a permanent replacement for the National Security Adviser role, and it remains unclear how long Rubio will serve in both capacities.
The position of National Security Adviser is one of the most influential in the executive branch, advising the president on intelligence, defense, and diplomatic affairs. Notably, the role does not require Senate confirmation, allowing Trump to make changes with minimal legislative friction.
Waltz’s expected nomination to the United Nations may serve as a graceful exit from controversy, preserving his public image while shifting him to a high-profile but less central role. However, questions remain about the Signal chat incident and whether more fallout could follow.
As Trump recalibrates his national security strategy, the Rubio appointment sends a clear message: in this White House, loyalty and alignment with the president’s agenda are non-negotiable. -MalayaDailyToday
