Stephen Miller Named White House Chief of Staff as Trump Shakes Up Team After Midterm Defeat

President Donald Trump has named Stephen Miller as his new White House chief of staff, replacing Susie Wiles in the most significant staff shake-up of his second term. Trump announced the change on Friday 6 November 2026, three days after Democrats won both chambers of Congress in the midterm elections, and Miller will take over on Monday 9 November.

Wiles, the first woman to serve as White House chief of staff, submitted her resignation on Thursday evening and will move to Trump’s political operation. Trump praised her work while making clear he wanted a change, telling reporters: “Stephen’s been with me from the beginning. He gets it. Very good, politically.”

Stephen Miller Appointment — Key Facts at a Glance

A Friday Announcement After a Bruising Tuesday

The shake-up is the first major personnel move since Republicans lost control of the House and Senate on Tuesday 3 November, with the Associated Press calling both chambers for the Democrats the following day. Trump told CBS’s 60 Minutes, in an interview taped on Friday before the announcement, that he intended to fire more people, answering “I do” when asked directly.

Wiles had become a target of Steve Bannon and other MAGA allies after the midterm losses, CNN reported, and two sources told the network she submitted her resignation on Thursday evening. Trump said Wiles “has done an outstanding job” and confirmed she would move to his political operation.

From Campaign Speechwriter to the President’s Gatekeeper

Miller joined Trump’s 2016 campaign as a speechwriter and wrote the campaign’s first immigration policy paper in 2015. He served as senior policy adviser in the first term and wrote the 2017 inauguration address, after working as communications director for then-Senator Jeff Sessions.

Since January 2025 he has been deputy chief of staff for policy and homeland security adviser, making him one of the most powerful figures in the West Wing. Reuters describes the chief of staff as the president’s gatekeeper, controlling access to the Oval Office and the flow of decisions. Miller marked the announcement on X on Friday, writing: “It has been the privilege of my lifetime to have served on his team from Day One, and I am honored beyond words to serve as his White House Chief of Staff.”

What the Promotion Means for Immigration Enforcement

Miller is widely recognised as the architect of the administration’s hardline immigration agenda. Last year he directed immigration officials to meet a daily quota of 3,000 arrests, an unprecedented figure that the agency struggled to reach, according to CNN. His elevation signals that Trump does not intend to moderate his approach as a Democratic-controlled Congress takes shape.

A Reuters/Ipsos poll found 36% of Americans approve of the immigration crackdown and 54% disapprove. That split explains why the appointment is read in Washington as a doubling down rather than a reset, with Miller now holding the post that manages the president’s agenda, staff and daily decisions.

Divided Government Awaits the New Chief of Staff

The new Congress convenes in January 2027, with Democrats holding both chambers and the power to set the legislative agenda and open investigations into the administration. Miller himself is expected to be a leading target of Democratic inquiries, according to Associated Press reporting, which puts the new chief of staff at the centre of the confrontation between the branches.

Trump has already ruled out firing Defence Secretary Pete Hegseth after the midterm defeat, praising his work despite Republican anger over the Iran war. The two decisions together show a president keeping his closest loyalists in place while preparing for two years of divided government, with Miller as the official who will have to manage that daily friction.

Wiles’s Exit Closes the Longest-Serving Tenure of the Term

Wiles was the administration’s longest-serving chief of staff and the first woman to hold the job. Her departure ends a tenure that spanned the opening phase of the second term, and her move to the political operation keeps her inside Trump’s orbit rather than outside it.

The test for Miller starts on Monday. He takes charge of a White House that has just lost its congressional majority, faces a Democratic investigation agenda and must decide how far executive action can carry a programme that Congress will no longer pass. USA Today reported that the move marks the most significant White House personnel change of Trump’s second term, and a signal that he is not ready to retreat from his agenda.
