Stephen Miller replaces Susie Wiles as Trump's chief of staff after the midterm rout
The architect of the mass-deportation drive takes over the White House on Monday 9 November. Wiles resigned on Thursday night and moves to the president's political operation, while Democratic leaders who will run both chambers from January promise to fight him.
Stephen Miller is the new White House chief of staff. Donald Trump announced the change on Friday afternoon in a post on Truth Social, as NBC News reported: Miller, until now deputy chief of staff, takes over on Monday from Susie Wiles.
Wiles handed in her resignation on Thursday night, according to a White House official quoted by NBC. Trump praised her work and said she would move over to his political operation.
The switch comes three days after Republicans lost both the House and the Senate in the 3 November midterms.
Who is Stephen Miller?
He is the adviser behind Trump’s immigration policy, including the second-term mass-deportation campaign. He has been with Trump since the first campaign in 2016, and inside the White House he is known as a loyalist and a hard taskmaster. In May 2025 he pressed Immigration and Customs Enforcement chiefs to reach 3,000 arrests a day.
On X, Miller thanked Wiles and wrote that the mission now is to fight “with all of our soul” for the president.
Why is Miller’s appointment being read as a message?
Because it runs the other way from what voters said. In NBC’s exit poll, 57% said Trump’s immigration enforcement had gone too far, against 23% who called it about right and 21% who wanted more.
Rather than a consensus pick, Trump has chosen the figure most closely tied to the MAGA base for his last two years. In mid-October he had told NBC that Wiles would stay “until the end”.
How did Democrats react?
Badly. Hakeem Jeffries, expected to become Speaker in January, said Miller should be fired, not promoted. Chuck Schumer, the Senate Democratic leader, said Trump had “learned nothing” from the defeat and promised the new majority would fight Miller “every step of the way”.
With both chambers in opposition hands from January, the chief of staff also becomes the White House’s main point of contact with a hostile Congress, including the investigations Democrats are already lining up.
