Trump taps Stephen Miller as chief of staff after GOP loses Congress

President Donald Trump has appointed Stephen Miller as White House chief of staff, replacing Susie Wiles, days after Republicans lost control of Congress in Tuesday's midterm elections. Trump announced the decision on Truth Social Friday, with Miller assuming the role Monday, November 9, 2026. Miller, currently deputy chief of staff for policy and a homeland security adviser, has been a central figure in shaping the administration's hard-line immigration policies, including its deportation agenda. Wiles, the first woman to hold the position, confirmed her departure on X, saying Friday was her last day, though she pledged continued commitment to Trump's mission. Wiles, a veteran strategist and the longest-serving chief of staff in Trump's presidency, disclosed a breast cancer diagnosis in March 2026 but indicated in October there was no longer evidence of the disease. She will move to Trump's political organization, while Miller, a longtime adviser since the 2016 campaign, takes charge amid the midterm fallout.
