An NPR article by Danielle Kurtzleben, posted November 6, 2026, reports that President Trump announced on social media that Stephen Miller will replace Susie Wiles as White House chief of staff, taking over the Monday after the announcement. The change follows Republicans' loss of power in the midterm elections; Wiles, who served since the start of Trump's term and was treated for breast cancer earlier in 2026, is succeeded by his deputy chief of staff, a fixture in Trump's circles since 2016 and an architect of his immigration policies.
