WASHINGTON, D.C. — President Donald Trump announced Friday that Stephen Miller will become White House chief of staff Monday, November 9, replacing Susie Wiles.

Miller currently serves as deputy chief of staff and has been a central figure in the administration’s immigration enforcement policies. Trump said Wiles would move to his political organization and praised her service.

Wiles said Friday was her last day in the White House position. CBS News reported that she submitted her resignation Thursday night.

The change comes days after Republicans lost control of Congress. Wiles, who helped run Trump’s 2024 campaign, was the first woman to serve as White House chief of staff and his longest-serving chief of staff across his two administrations.
