President Trump has installed longtime adviser Stephen Miller as White House chief of staff and moved Susie Wiles to his political operation after Republicans lost both chambers of Congress, a change allies say signals a harder fight ahead.
President Trump announced Friday that Stephen Miller, his deputy chief of staff and one of his closest policy hands, will take over as White House chief of staff starting Monday, November 9, 2026.
The Post reported that Susie Wiles, who managed Trump’s successful 2024 campaign and served 21 months as chief of staff, is moving to the Trump Political Operation. The shift follows Republican losses in the House and Senate and comes as the administration prepares for Democratic investigations next year.
Trump made the change public on Truth Social, praising both aides and framing the move as orderly rather than punitive.
"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,"
Trump added in the same post:
"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!"
Miller, 41, has worked for Trump since the day he entered the White House in 2017. He served as a top speechwriter in the first term, later as homeland security adviser, and in the second term as deputy chief of staff for policy.
Fox News reported that Wiles is departing after 21 months, Trump’s longest-serving chief of staff in this term, and that the announcement followed the party’s midterm defeat in both chambers.
A source close to Wiles said she tendered her resignation the day before Trump’s post. Wiles, 69, was diagnosed with breast cancer during her tenure and has been credited inside the building with bringing stability and cohesion to the West Wing.
In her own statement she struck a loyal note.
"Serving President Trump in the White House has been the honor of a lifetime. I’m so proud to have been a part of what we’ve accomplished together from securing our border and cutting taxes to strengthening our economy and putting America First. More than anything, I’m grateful for the extraordinary people I’ve had the privilege of working alongside. While my role may be changing, my commitment to the President and the mission never will."
A White House official told reporters ahead of the announcement that the administration still has people ready for the next phase.
"There are still many who are gearing up for the challenge. It’s time to fight even harder."
An operative close to the White House said Miller’s elevation signals Trump is gearing up for a fight with Democrats. Miller has rarely leaked to the press, often defended the president on television, and served as a key conduit to federal agencies.
His second-term portfolio has ranged from advancing the administration’s deportation agenda to overseeing the release of declassified UFO files. In the past month he has appeared with Trump at events focused on anti-fraud efforts and cybercrime.
At an October 21 event in the East Room, Miller addressed the president directly and praised the record on trade, welfare fraud, and cybercrime.
"You’ve put the American people’s safety first. There’s a common theme in all of the challenges that you have systemically tackled and solved, whether it’s the trade deficit, where we were getting ripped off by foreign countries, whether it’s welfare fraud, where we’re getting ripped off by these refugees and foreign scammers, or cybercrime, where you have entire foreign economies that are propped up on stealing from American seniors. What you’re saying is America is not a pile of treasure for other countries and other people and other scammers all around the world to loot for themselves. You’re protecting American wealth for American people and American families in a way no leader has ever done before."
Just The News reported that some conservative hawks had criticized Wiles for moderating hardline policies, and that Miller is widely viewed as an immigration and deportations hawk who has pushed uncompromising agendas. Whether the personnel change produces a sharp policy turn remains unclear from the available accounts.
Trump’s public language treated the handoff as a promotion for both: Miller into the top staff job, Wiles into the political operation that will matter as Democrats gear up their committee work.
Other names have circulated as possible further changes after the midterm loss, including War Secretary Pete Hegseth and Adm. Brad Cooper, the U.S. Central Command chief, over their roles connected to the Iran war. No formal action on those posts was announced alongside the Miller elevation.
Miller’s wife, Katie Miller, has served as an official in both Trump terms. The new chief of staff is known inside the building for loyalty, message discipline, and a willingness to defend the administration’s hardest edges in public.
Wiles leaves the daily West Wing grind having run a winning national campaign and having held the staff job longer than any other chief in this term. She moves to political work with the president’s public thanks still attached to her name.
Miller starts Monday with a narrower brief in one sense and a broader one in another: run the building, keep the agencies aligned, and prepare the White House for a Congress now controlled by the opposition.
Personnel is policy, and this personnel choice puts a trusted fighter at the center of the next two years.
