WASHINGTON (AP) — President Donald Trump said Friday that Stephen Miller was replacing Susie Wiles as White House chief of staff, mere days after Republicans lost control of Congress in the midterm elections.

On his social media site, Trump praised Wiles and said she’d continue to work for his political organization.

“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. 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!” Trump wrote on Truth Social.

Miller, long a key member of Trump’s inner circle, is a key architect of the administration’s hard-line immigration policies.

Wiles, the steely political operator and longtime adviser to Trump, was the first woman to ever serve in that post.

Wiles’ departure comes almost immediately after the GOP’s midterm thrashing on Tuesday. She will be replaced by Stephen Miller, a longtime trusted aide to Trump.

The departure also came months after Wiles indicated she no longer showed evidence of breast cancer after she underwent months of treatment for the disease, a diagnosis she went public with in March 2026.

Wiles is the longest-serving White House chief of staff for Trump, who cycled through four of them during his first four-year term.
