Trump Ousts Chief of Staff Susie Wiles, Installs Immigration Hard-Liner Stephen Miller After Midterm Rout

President Trump ousted Susie Wiles as White House chief of staff on Friday and replaced her with Stephen Miller, his longtime policy aide and the chief architect of the administration's mass-deportation campaign, in the most significant shake-up of his senior team since Republicans lost control of Congress three days earlier.

Trump announced the change on Truth Social, and confirmed it to reporters afterward. "I wanted to make a change," he said, while praising Wiles for doing "a very good job, great job" and adding that she would move to the Trump political operation. Wiles, according to CBS News, submitted her resignation Thursday night; Friday was her last day in the role. Miller, currently deputy chief of staff for policy, takes over the post on Monday. The reversal was abrupt: as recently as mid-October, Trump had told reporters Wiles would stay "until the end" of his term.

A Resignation Tied to the Midterms

Three people familiar with the matter told CBS News that Wiles's departure was directly tied to Republicans' losses in Tuesday's midterm elections, in which Democrats flipped both the House and the Senate. Democrats had secured 253 of the House's 435 seats as of Friday, with 27 races still uncalled, and netted seven Senate seats, with counting still underway in Alaska and Mississippi, according to a tally reported by Al Jazeera. NBC News reported that Wiles had privately planned to stay through Congress's lame-duck session and depart around the end of the year or early 2027, but Trump accelerated her exit. Wiles, 69, had survived months of swirling reports that Trump was shopping for her replacement — reports the White House repeatedly denied — and had disclosed in September that she was cancer-free after treatment for an early-stage diagnosis. She had served longer than any of the four chiefs of staff who cycled through Trump's first term.

Wiles, who ran Trump's 2024 campaign, wrote on social media that serving in the role had been "the honor of a lifetime" and cited border security, tax cuts and "America First" policy as accomplishments. It remains unclear whether her deputies will stay on under Miller. Notably, the switch was announced through a social post rather than a written release: the White House's own running list of formal statements and releases carried no mention of the personnel change as of Friday evening.

The Architect of Deportation

Miller has been one of Trump's closest aides since the 2016 campaign, after working on Capitol Hill for Sen. Jeff Sessions. In his current post as deputy chief of staff for policy and homeland security advisor, he has driven the administration's immigration enforcement machinery, reportedly berating Immigration and Customs Enforcement officials last year over arrest numbers and demanding roughly 3,000 detentions a day. He had kept a lower public profile since January, after federal agents in Minneapolis killed two U.S. citizens, Renee Good and Alex Pretti; Miller had wrongly branded Pretti a "domestic terrorist" in a post before the White House acknowledged it had acted on faulty information from Customs and Border Protection. At a gathering at Mar-a-Lago after his new role was settled, Miller pledged "absolute loyalty" to Trump and wrote separately on social media that the mission now is to "fight with all of our soul" for the president.

Polling suggests the public has soured on that agenda. In NBC's exit poll from Tuesday's election, 57% of voters said Trump's immigration enforcement has gone too far, against 23% who called it "about right" and 21% who said it had not gone far enough — a split that several Trump allies and strategists cited as evidence the party misjudged the political moment even as Miller's influence grows inside the West Wing.

Democrats Vow a Fight

The appointment landed just as Democrats were formally organizing to take control of Congress. House Democratic Leader Hakeem Jeffries, who announced his candidacy for speaker in a letter to colleagues on Wednesday, called Miller a "dangerous xenophobe" and said his presence in government should be "eradicated." Rep. Robert Garcia, in line to chair the House Oversight Committee once Democrats take the gavel, said Miller "should lawyer up," vowing investigations into his conduct.

"Donald Trump has learned nothing" from the midterm defeat, Senate Democratic Leader Chuck Schumer said, vowing that incoming Democratic majorities "will fight him every step of the way."

Reaction split sharply along party lines. Steve Bannon, the former Trump strategist, said of Miller's ascent that he "gets parachuted in and takes immediate control," while Republican strategist Mark Bednar called him "a tireless, meticulous tactician." A former administration official, granted anonymity to discuss internal dynamics, said the move was intended to reassure a Republican base that had grown distrustful of Wiles, while a person close to the White House said the appointment "sends the right message to the base."

For now, the day-to-day apparatus of Congress has not caught up with the election results: the Senate's own public roster still lists the outgoing 119th Congress's party breakdown of 53 Republicans to 45 Democrats and two independents, a tally that will shift substantially when the new Congress is seated in January.

What Comes Next

Miller is due to formally start as chief of staff on Monday, taking over an operation that will soon face a Democratic-controlled Congress for the first time in Trump's second term. Jeffries and other Democratic leaders have already signaled they intend to use subpoena power and committee investigations to target Miller directly once they organize the chamber in January. Trump has given mixed signals about how far any wider shake-up will go: in a "60 Minutes" interview he said he might make "maybe a few changes" to his Cabinet, but he has more recently said he expects "very little" turnover elsewhere in his administration, even as he reshapes the office that sits closest to him. Whether Wiles's own deputies remain at the White House, and how much latitude Miller is given to reshape its operations beyond immigration policy, are likely to be the first tests of how far the shake-up extends.
