Trump Names Stephen Miller White House Chief of Staff Replacing Susie Wiles

President Donald Trump announced on Friday that Stephen Miller will replace Susie Wiles as White House chief of staff, effective Monday. Trump made the statement in a Truth Social post after Wiles submitted her resignation on Thursday evening.

Wiles has served as chief of staff since the start of Trump's second term. She will move to the president's political operation. Trump described her as having done an outstanding job and said he wants to thank her for her service.

Miller has worked as deputy chief of staff for policy and has long shaped the administration's immigration enforcement and deportation efforts. He has been one of Trump's closest aides for years. Trump called him one of his most trusted advisors and said he is very good politically and a great manager.

The change comes days after Republicans lost control of both the House and the Senate in the midterm elections. Sources familiar with the matter said Wiles's resignation was tied to those defeats. Trump has voiced anger over the strategy that produced the losses.

Elevating Miller signals that the president does not plan a major shift in governing approach. Miller has driven hardline positions on immigration and has faced repeated criticism for his role in those policies. The move is the first major staff shakeup after the midterms.

Wiles, a longtime Florida operative, managed Trump's 2024 campaign and then ran the West Wing. Her departure leaves open questions about continuity for other senior aides. It remains unclear whether her deputies will stay in place.

The announcement followed reports that Trump remained furious about the election results. Democrats secured majorities in both chambers, with gains in states including Texas, Kansas, and Ohio. Several Republican incumbents lost seats in districts that had previously leaned toward the party.

Miller's elevation places a figure closely associated with the administration's most restrictive immigration measures at the center of daily operations. He has coordinated efforts to expand deportations and to pressure states on voting data. His new role gives him broader authority over White House staffing and scheduling.

Trump told reporters that Miller would begin on Monday. The timing leaves little transition period. Wiles is expected to focus on political activities outside the formal White House structure.

The staff change arrives as the administration faces a divided Congress starting in January. Democrats have already signaled plans to scrutinize executive actions and to push legislation on health care costs and other issues that dominated the campaign. Miller's appointment suggests the White House will continue to prioritize enforcement and restrictive measures on immigration even without legislative majorities.

Officials familiar with the discussions said the decision crystallized after Tuesday's results became clear. Trump had defended the campaign strategy publicly but expressed private dissatisfaction with the outcome. The elevation of Miller places a trusted loyalist in the position that controls access to the president and coordinates agency work.

Miller's portfolio has included drafting executive orders on border enforcement and coordinating with the Department of Homeland Security. In his new role he will oversee a larger set of priorities, including budget negotiations with the incoming Democratic Congress and the response to ongoing conflicts abroad. The move does not require Senate confirmation.

Wiles's transfer to the political operation keeps her involved in Trump's broader network. She retains influence outside the formal government structure. The arrangement allows the president to maintain a trusted campaign manager while installing a policy operator in the West Wing.

Congressional Democrats reacted by noting the continuity in approach. They said the choice of Miller indicates the administration will not moderate its positions on immigration or other contentious issues. Republican allies described the appointment as a recognition of Miller's loyalty and operational skill.

The transition takes effect on Monday. Until then Wiles remains in the role. The White House has not released a full list of other personnel changes that may accompany the shift.
