Trump appoints Stephen Miller as chief of staff after midterm losses

Stephen Miller will become White House chief of staff on Monday, replacing Susie Wiles, President Donald Trump announced on Friday via Truth Social. Trump said Wiles had done an “outstanding job” and will move to the Trump Political Operation. Wiles, 69, praised her time in the role as “the honor of a lifetime” and highlighted achievements such as border security, tax cuts, a stronger economy and the America First agenda. She also noted that her commitment to the president will not change despite the new position. Miller, a deputy chief of staff and longtime ally, is described as the architect of Trump’s hard‑line immigration policy and served as a senior adviser in the first Trump administration. The change comes three days after Republicans suffered major defeats in the 2026 midterm elections, losing control of both the House and the Senate. Earlier this month Trump told reporters there was “zero chance” Wiles would be replaced and that she would stay “for a long time.” Wiles recently announced in September that she was in remission following a cancer diagnosis six months earlier. The president called Miller “one of my most trusted advisers” and said he would assume the top job on Monday. ## Context The White House chief of staff runs the president’s daily schedule and oversees the staff, making the role key to implementing policy. Changes in the position are common after election cycles as presidents adjust their teams. Miller’s hard‑line stance on immigration signals a continued focus on that issue.
