President Donald Trump is elevating Stephen Miller to White House chief of staff, putting one of his most trusted advisers in charge of his staff as Susie Wiles moves to his political operation. Trump announced the change Friday, November 6th, with the transition taking effect the following Monday. The appointment promotes an official closely associated with the president’s MAGA agenda.
The announcement came through a Truth Social statement outlining the personnel change and thanking Wiles for her service. Miller already serves inside the administration as deputy chief of staff, giving Trump a successor drawn from his existing leadership team. The president described Wiles’ next assignment as a move to the “Trump Political Operation,” where she will continue working for him.
The change follows Tuesday’s midterm elections, in which Republicans lost control of Congress. Wiles had served as chief of staff since Trump returned to the White House in January 2025, after helping run his successful presidential campaign. Miller also worked on that campaign and previously served as a senior policy adviser during Trump’s first term in office.
In the announcement shared in Kyle Cheney’s post on X, Trump identified his choice and provided the effective date. “I am pleased to announce that Mr. Stephen Miller, the current Deputy Chief of Staff of the Trump Administration, and one of my most trusted advisors, will become the Chief of Staff starting Monday, November 9, 2026,” the president wrote.
Miller’s second-term responsibilities have included serving as homeland security adviser alongside his role overseeing policy. Trump’s transition team announced those appointments on November 13th, 2024, as part of a senior staffing rollout that also included Dan Scavino, James Blair and Taylor Budowich. The announcement identified all four as advisers from his winning campaign. “They will continue to work hard to Make America Great Again in their respective new roles,” Trump said at the time.
Since returning to the White House, Miller has held a broad portfolio that includes helping design the administration’s immigration enforcement and deportation program, CBS News reported. His work on immigration also stretches back to the first Trump administration. The White House featured him in an October 12th video titled “President Trump’s Second Term: Stephen Miller,” released several weeks before Friday’s announcement.

Wiles was the first woman to hold the White House chief of staff position and became Trump’s longest-serving chief of staff, the Associated Press reported. Trump cycled through four people in that role during his first four-year term. Her departure from the position comes after she continued working through breast cancer treatment following a diagnosis made public in March.
Trump included a personal acknowledgment of Wiles in Friday’s statement as he outlined her next assignment. He credited her performance during her time leading the White House staff and thanked her directly. “Susie Wiles, who has done an outstanding job, will be moving over to the Trump Political Operation. I want to thank her for her service as Chief of Staff — She has done a great job!”
