Stephen Miller, President Donald Trump's deputy chief of staff and the main architect of his immigration crackdown, takes over as White House chief of staff on Monday, Nov. 9. He replaces Susie Wiles, who submitted her resignation Thursday night, two days after Republicans lost control of both chambers of Congress in the midterms.

Why it matters: Miller designed the mass-deportation campaign behind ICE arrests in Bay Area cities, and he takes one of the most powerful jobs in Washington as Democrats prepare to lead the House and Senate in January, NBC News reported.

What happened

Trump announced the change on Truth Social Friday afternoon. The White House called Miller the 33rd chief of staff and said he "has been a driving force behind the Administration's major successes." Trump said Wiles "has done an outstanding job" and will move to the Trump political operation. Wiles, 69, was the first woman to hold the job.

"It is the honor of my life to be President Trump's chief of staff," Miller said Friday night at Mar-a-Lago, pledging "my absolute loyalty."

Reaction

Vice President JD Vance called Miller "an amazing patriot." House Minority Leader Hakeem Jeffries, expected to become speaker in January, called for Miller to be fired, and Senate Minority Leader Chuck Schumer said Trump "learned nothing from his historic defeat."

In May 2025, Miller pushed Immigration and Customs Enforcement to reach 3,000 arrests a day, NBC reported. In the NBC News Exit Poll, 57% of midterm voters said Trump's immigration enforcement has gone too far.
