Trump names Stephen Miller chief of staff after US midterm losses, replaces Susie Wiles

US President Donald Trump has appointed his longtime aide Stephen Miller as the new chief of staff, replacing Susie Wiles, in the wake of Republican losses in the recent midterm elections. The announcement was made on Trump's social media platform, Truth Social, on Friday, with Miller set to assume the role starting Monday, November 9, 2026. Trump praised Miller, stating that he is "pleased" to have him as Chief of Staff and a trusted advisor.

Wiles, who became the first woman to serve as White House chief of staff, thanked Trump for her service, noting she "has done an outstanding job." She confirmed her departure on X, expressing pride in her accomplishments with Trump, including border security, tax cuts, and economic growth. Wiles emphasized that her commitment to the President and the mission will remain unchanged despite the change in her role.

The leadership shift follows Republican setbacks in the midterm elections, where they lost control of Congress. Wiles had reportedly been considering leaving the position after the elections. Trump had previously dismissed speculations about her replacement in mid-October, stating there was "zero chance" he was considering such a move.

Miller, a close and long-serving advisor to Trump, has been instrumental in shaping the administration's hardline immigration policies. He currently serves as Deputy Chief of Staff for Policy and Homeland Security adviser. Miller joined Trump's 2016 presidential campaign as a speechwriter and has since held various roles in the administration.

Wiles, a veteran political strategist and longtime Trump adviser, was the longest-serving White House chief of staff during Trump's presidency, following four different chiefs. Her departure comes months after she disclosed her breast cancer diagnosis in March 2026. After months of treatment, she announced in October that there was no longer evidence of the disease.

Miller's appointment places him in a central coordinating role within the White House, especially as the administration navigates the political consequences of the midterm results. Wiles is expected to continue her work with Trump through his political operation, starting from November 9.
