President Donald Trump has made the biggest shake-up of his team since the midterms by naming Stephen Miller as his new White House chief of staff, announcing it Friday, November 6. Miller, who is currently deputy chief of staff for policy, will take over from Susie Wiles on Monday, November 9. Trump praised him as "a great fighter" who has been loyal and smart since the very beginning, called him an MVP, and said he has gotten great reviews. He also described Miller as very good politically and a great manager, and said simply that he "wanted to make a change." Wiles, the first woman to hold the job, is moving over to what Trump called the Trump Political Operation, and Trump thanked her for an outstanding job.

The announcement comes just days after Republicans lost control of Congress in the midterm elections, and news outlets have read it as a message about how Trump plans to govern next. Miller is best known as the architect of the administration's hardline immigration policies, and he also serves as homeland security advisor. CBS News described the move as a doubling down on Trump's approach despite voters' rejection on Tuesday, and Newsweek said it could signal more reliance on executive action over the next two years. Supporters inside the administration, including EPA chief Lee Zeldin, praised Miller as a fighter who has been at Trump's side from day one. The big questions now are how Miller will run a West Wing that Wiles was known for keeping disciplined, and how far executive action can go once Democrats take over Congress in January.
