President Donald Trump has named Deputy Chief of Staff Stephen Miller to replace Susie Wiles as White House chief of staff on Nov. 9, after Republicans suffered heavy losses in the midterm elections.
Trump announced the change on Friday, Nov. 6. He said Wiles would move to his political operation. He described Miller as one of his most trusted advisers.
He told reporters he wanted a change. He praised both Wiles’ work and Miller’s performance. Wiles submitted her resignation on Thursday night, according to White House officials cited by news outlets.
CBS News reported that sources connected her departure to the Republican defeats. Miller, a longtime Trump ally, has served as deputy chief of staff. He helped shape the administration’s immigration enforcement and deportation policies.
His promotion puts a prominent hard-line voice at the center of White House operations. Democrats are preparing to take control of Congress. Wiles, who managed Trump’s 2024 presidential campaign, had been chief of staff since he returned to the White House in January 2025.
She said Friday was her last day as chief of staff. She expressed gratitude for her time in the administration. The appointment is being seen as a sign that Trump plans to continue his current agenda, not change course in response to the election setback.
Miller’s promotion is also likely to increase tensions with Democrats, who have criticized his role in the administration’s immigration policies.
