Trump names Stephen Miller chief of staff, replacing Wiles

U.S. President Donald Trump announced Friday, Nov. 6, 2026, that Susie Wiles is leaving as White House chief of staff and that his top aide Stephen Miller will replace her, days after Democrats won control of Congress.

Wiles served 21 months in the job, the longest tenure of any chief of staff in Trump’s two terms, Fox News reported. The change puts the White House’s top staff post in new hands as the administration faces a Democratic House and Senate for the first time in the second term.

Trump announced the change in a written post on Friday, ABC News reported. Fox News reported that Trump wrote that Wiles “has done a great job” and thanked her for her service. Fox also reported that Trump called Miller one of his most trusted advisers.

Miller will take over the role on Monday, Nov. 9, Fox reported. Wiles is moving to Trump’s political operation, according to the same report. ABC News described the story as developing, and neither report included a statement from Miller.

Miller held the title of White House deputy chief of staff for policy, according to official government photo captions from 2025. NPR, The Washington Post, Axios and The Hill also reported the change on Friday.

Fox said Wiles is leaving after Republicans lost control of the House and the Senate in the Nov. 3 midterm elections. Canada News Media reported on the Democratic Senate win and what it means for Canada on election night.

For Canada, the change comes while trade talks with Washington remain unresolved. Canada News Media reported before the vote that no Canada-U.S. trade deal was expected before the midterms. On Nov. 6, Prime Minister Mark Carney said Canada welcomes any U.S. move to restore free trade.

None of the reports reviewed by Canada News Media said whether the staffing change affects Canada-U.S. trade policy or the tariffs now in effect, which are set out in our guide to Canada tariffs and what they cost. No Canadian government reaction to the change had been reported at the time of publication.

The reports reviewed by Canada News Media did not say who will fill the deputy chief of staff for policy post Miller held. This story will be updated as details are confirmed.
