Stephen Miller Replaces Susie Wiles as White House Chief of Staff in Trump's First Post-Election Shake-Up
President Trump announced Friday that Stephen Miller, his deputy chief of staff and the architect of his hardline immigration agenda, will become White House chief of staff on Monday. Susie Wiles, the first woman to hold the job, submitted her resignation Thursday evening and will move to Trump's political operation.
The first major White House shake-up since Tuesday's midterm rout landed on Friday afternoon. President Donald Trump announced on Truth Social that Stephen Miller will replace Susie Wiles as White House chief of staff, effective Monday, November 9. '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 wrote. '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!'
Wiles submitted her resignation on Thursday evening, according to CNN's reporting from two sources familiar with the matter, after a week in which Trump voiced fury at the strategy that led Republicans to decisive losses of both the House and the Senate. Wiles, a longtime Florida Republican operative who managed Trump's 2024 campaign and became the first woman ever to serve as White House chief of staff, said in a statement on X that serving Trump was 'the honor of a lifetime.' 'While my role may be changing, my commitment to the President and the mission never will,' she added. Wiles recently announced she had completed treatment for breast cancer, and said in September that she was cancer-free.
The choice of successor is the story's sharpest signal. Miller, a deputy chief of staff who has worked for Trump since his first campaign began in 2015, is the mastermind of the administration's hardline immigration agenda, and over the past year he has widened his portfolio to include wide swaths of domestic policy while advocating an expansive view of executive power, CNN reports. Elevating him to the top staff job in the West Wing reads less like a change of direction than a decision to press the same agenda harder, now against a Congress his party no longer controls.
The move takes effect Monday, and it may not be the last: the announcement is the first major personnel change of the post-election period, and it lands as the administration absorbs a defeat that cost it both chambers. For Houston, the elevation matters in a specific way - the official who designed the immigration enforcement policies that Houston police policy has spent this week adjusting to will now run the White House's entire domestic operation.
