President Donald Trump announced on Friday, November 6, 2026, that Stephen Miller will become the new White House chief of staff. Miller, who currently serves as deputy chief of staff, will replace Susie Wiles in the position starting Monday, November 9, 2026.
The personnel change follows the November 3 midterm elections, in which the Republican Party lost control of the House of Representatives and the Senate. The Republican party also lost dozens of governorships and state legislatures. Wiles has served as chief of staff since the beginning of the current administration, having previously managed the president’s 2024 campaign.
In a statement on Truth Social, the president described Miller as one of his "most trusted advisors" and said Wiles had done an "outstanding job." Wiles confirmed on social media that Friday was her last day in the role, stating she would move to the president’s political operation. She cited the administration's work on border security, tax cuts, and the economy as accomplishments.
Miller, 41, has been a long-term aide to the president and a primary designer of the administration's immigration enforcement and mass deportation programs. Miller has also advocated for policies that would deny federal funding to jurisdictions that elect Democratic officials.
The transition places the person responsible for the administration's immigration and deportation programs into the highest-ranking staff position in the White House. Under Miller's leadership, the administration's focus on mass deportations and "America First" initiatives is expected to continue or accelerate. Miller has also pushed for policies meant to make it more difficult for anyone from non-white-majority countries to immigrate to the United States.
The shift of Wiles to the "Trump Political Operation" follows the loss of congressional majorities. Miller officially assumes his duties on November 9, 2026, at which point he will oversee the White House staff.
