White House Staff: Stephen Miller Succeeds Susie Wiles

Stephen Miller takes over as White House chief of staff this Monday.

President Donald Trump announced the promotion on Friday, replacing Susie Wiles in the role. The change places Miller, who serves as deputy chief of staff, at the top of the executive branch staff hierarchy. He will assume his new duties starting Monday, according to a post on Truth Social.

Miller has served as a primary architect for the administration's mass deportation initiatives. His new role positions him directly in front of a newly empowered group of congressional Democrats. These lawmakers gained majority control of both the House and Senate during the midterm elections held earlier this week. They have pledged to scrutinize government immigration policies closely during their tenure.

Trump described Miller as one of his most trusted advisors in the official announcement. He noted that Wiles, who managed the 2024 presidential campaign, will move to the Trump Political Operation. The organization’s official account on X shared a black and white photo of Miller with the caption, "It's Miller time."

Wiles confirmed her departure in a post on X on Friday afternoon. She stated that today is her last day as White House Chief of Staff. A senior White House source told MS NOW that Wiles resigned on Thursday night. The report indicated she told the president, "Let me make this easy on you - I am going to resign."

Trump explained the decision to reporters while leaving for an event in Cape Canaveral, Florida. He said he wanted to make a change and believed Wiles had done a very good job. He added that Miller has been great and that sometimes in life one has to make moves.

The staffing shift occurs after several high-level departures at the Department of Justice since Election Day. Harmeet Dhillon, who led the civil rights division, John Eisenberg, who headed national security, and Jason Reding Quiñones, who managed conspiracy investigations, have all left their posts. Wiles had previously drawn public attention in late 2025 after Vanity Fair reported she described the president as having an alcoholic's personality.

Wiles expressed in her farewell message that serving the president has been the honor of a lifetime. She noted her commitment to the mission remains unchanged despite the change in her role. Miller's elevation marks the first major leadership change in the executive branch following the Democratic midterm victory.
