"I am pleased to announce that Mr. Stephen Miller, the current Deputy Chief of Staff of the Trump Administration, and one of my most trusted advisors, will become the Chief of Staff starting Monday, November 9, 2026," Trump wrote on Truth Social. "Susie Wiles, who has done an outstanding job, will be moving over to the Trump Political Operation. I want to thank her for her service as Chief of Staff — She has done a great job!"

Wiles was the first woman to serve as White House chief of staff. Her move out of the West Wing, and Miller's elevation, mark the most senior personnel change in the administration since Republicans lost the midterm elections earlier this week, The Washington Sun reported.

Miller, a longtime Trump confidante who has served as an enforcer for the president since the beginning of his first term, has been one of the most influential figures in the administration, particularly on immigration policy. As chief of staff he will control the flow of paper and people to the president at a moment when the White House is regrouping after the midterm defeat.

The announcement was made in Trump's own post on his Truth Social account; the details above are the president's stated plan, reported by Bloomberg Government and The Washington Sun on Friday afternoon.
