In a significant shake-up, President Donald Trump has removed Mike Waltz from his post as national security adviser amid criticism over sensitive information and vetting concerns. Waltz is now nominated for the position of ambassador to the United Nations.
In a significant shake-up in the White House, President Donald Trump has removed Mike Waltz from his post as national security adviser. The decision comes amid criticism over Waltz’s handling of sensitive information and concerns about his vetting of National Security Council staff.
Mike Waltz is an American politician serving as the U.S. Representative for Florida's 6th congressional district since 2019.
He is a member of the Republican Party.
Prior to his election, Waltz served in the United States Army and was a Green Beret.
He also worked as a business consultant and investment banker.
Waltz holds a Bachelor's degree from Stanford University and an MBA from Harvard Business School.
Waltz will be temporarily replaced by Secretary of State Marco Rubio, who will continue to serve as the top diplomat in the administration. ‘The President has nominated me for a new role,’ said Rubio, ‘I am honored and ready to serve.’
Marco Rubio is an American politician serving as the senior United States Senator for Florida since 2011.
He previously served in the Florida House of Representatives from 2000 to 2008 and was the Speaker of the Florida House from 2007 to 2008.
Born on May 28, 1971, in Miami, Florida, Rubio earned a Bachelor's degree in Law and a Master's degree in Public Administration.
He ran for President in 2016 but dropped out after Super Tuesday.
Rubio is known for his conservative views and has been a strong advocate for immigration reform.
Trump has nominated Waltz for the position of ambassador to the United Nations, a move that is seen as a soft landing for the embattled national security adviser. The removal of Waltz from his post is largely due to controversy surrounding his handling of sensitive information.
In March, it was revealed that ‘I’m not sure I would have added him to the chat,’ said Jeffrey Goldberg, editor-in-chief of The Atlantic magazine, who was added to a group chat on Signal with top US security officials. Confidential plans for a military strike on Yemen’s Houthis were discussed in the message chain, which also included Rubio and Defence Secretary ‘Pete Hegseth‘.
Waltz has acknowledged his mistake and taken responsibility for it. However, the incident raised concerns about his ability to properly vet National Security Council staff and handle sensitive information. The UN ambassador position remains unfilled, with Trump having withdrawn the nomination of his first pick, New York congresswoman ‘Elise Stefanik,’ amid Republican concerns about preserving their slender majority in the House of Representatives.
A Changing Landscape for National Security

Waltz’s departure marks a significant change in the White House’s national security landscape. The former Florida congressman is the first senior member of the administration to leave the White House in Trump’s second term.
The move has also raised questions about the president’s decision-making process and his ability to surround himself with trusted advisors. Critics have pointed out that Trump has a history of ousting his national security advisers, including ‘Michael Flynn’ and ‘John Bolton.’
Despite the controversy surrounding Waltz’s departure, Trump appears to respect him and has given him a high-profile new post as UN ambassador. However, it remains to be seen how successful Waltz will be in this role and whether he can overcome the challenges posed by his past mistakes.
A New Chapter for Rubio
Rubio’s appointment as acting national security adviser marks a significant shift in the White House’s approach to national security. The former senator has a reputation for being a strong advocate for US interests abroad and has been a key player in shaping Trump’s foreign policy agenda.
As acting head of both the United States Agency for International Development and the National Archives, Rubio will be tasked with overseeing a range of critical agencies that play a vital role in advancing US interests abroad. His appointment also raises questions about his ability to balance competing priorities and navigate the complexities of US foreign policy.
The Washington rumour mill is abuzz with speculation about who might replace Waltz as national security adviser. ‘Steve Witkoff,’ a real estate developer and personal friend of Trump, is reportedly in the running for the job. Ric Grenell, another special envoy to the Middle East, is also being mentioned as a potential candidate.
Regardless of who ultimately replaces Waltz, one thing is clear: the White House’s national security landscape is about to undergo significant changes.
