Trump replaces White House chief of staff with Stephen Miller after Republican midterm defeats
US President Donald Trump has announced that Stephen Miller will become his new White House chief of staff, replacing Susie Wiles in one of the most powerful jobs in the administration. The change was announced on Friday and marks a significant personnel shift at the centre of the US government. Wiles will move to the Trump political operation outside the White House, according to the announcement.

Miller has been serving as deputy chief of staff and is widely identified with some of the most hardline immigration measures from Trump's first term. Those policies included the push to build a wall on the US-Mexico border, a project that began but was not completed. The announcement places one of Trump's closest ideological allies in a role that helps coordinate the daily work of the presidency and the wider White House operation.
Wiles was the first person Trump announced for his second-term team and has been described as one of his most trusted advisers. She played a major role in Trump's political rise and remained close to him after the 2021 attack on the Capitol by his supporters. Her move away from the White House comes after a period in which she was also drawn into internal controversy following a December 2025 magazine profile that caused discomfort inside the administration.
The personnel change comes shortly after Republicans suffered major midterm defeats, including losing control of both chambers of Congress. That political setback increases the importance of the White House team as Trump seeks to manage the next phase of his presidency. A chief of staff is central to controlling access to the president, coordinating policy, and managing relations between the White House and other parts of government.

Miller's appointment also signals a possible hardening of the administration's approach on immigration and other core priorities. His record makes him one of the most recognisable figures in Trump's inner circle, and his promotion suggests continuity with the president's most combative political instincts. At the same time, moving Wiles to the political operation may help Trump keep a trusted organiser close while reshaping the White House chain of command.
It remains unclear whether the change will alter the administration's day-to-day style or policy direction beyond the symbolism of the appointment. The White House has not yet set out any further details on the timing of the transition or how responsibilities will be divided during the handover. What happens next will be watched closely for signs of how Trump intends to respond to the election losses and whether the new team structure changes the balance of power around him.
