Miller Replaces Wiles as White House Chief of Staff

Working families in the United States will see a shift in executive leadership this week. President Donald Trump announced on Friday that Stephen Miller will replace Susie Wiles as White House chief of staff. The change takes effect immediately following the Republican Party's loss of control over Congress in Tuesday's midterm elections.

Miller is a close aide who has been a central figure in the administration's hardline immigration policies. Trump described him as a trusted collaborator in the inner circle. The transition occurs less than a week after voters rejected the party's platform in what commentators have termed a blue tsunami.

Wiles held the position for the longest duration of any chief of staff during Trump's current term. She was the first woman to serve in that role. Her departure comes months after she reported that she no longer showed evidence of breast cancer. She made her diagnosis public in March 2026 and underwent several months of treatment.

Trump posted on social media that Wiles would continue working for his political organization. He praised her service despite the sudden turnover. The White House previously cycled through four different chiefs of staff during the president's first four-year term. Wiles' tenure had provided a period of relative stability in that office.

Miller now assumes control of the executive office operations. He will oversee the day-to-day management of the presidency. This move places a key architect of recent policy directives directly in charge of the West Wing. The administration did not provide a detailed timeline for Wiles' transition out of the building.
