Stephen Miller replaces Susie Wiles as Trump's chief of staff after midterm defeat

Abstract

Donald Trump named Stephen Miller, his deputy chief of staff, as White House chief of staff on 6 November 2026, replacing Susie Wiles, who is moving to Trump's political operation^[1,2]. The change followed Democratic victories in both chambers of Congress, with CBS News reporting at least 54 Senate seats and projecting between 251 and 268 of the 435 House seats^[3,4]. The NBC News exit poll recorded Trump's approval at 38 per cent, and 57 per cent of voters said immigration enforcement had gone too far^[5]. CBS News reported that people familiar with the decision linked the resignation of Wiles to the midterm defeats^[2]. The Associated Press described Miller as widely recognised as a chief architect of the administration's immigration policies, and reported that Democrats are poised to investigate the administration, with Miller a likely target^[6]. Supporters present the appointment as a more defiant turn, while some House Republicans and Democratic leaders criticise it^[7,8,9]. The next phase of the presidency will therefore pit the White House against a Congress that has said it intends to investigate the new chief of staff^[6,10]. The link between the resignation and the results rests on unnamed sources, estimates of the House majority range from 228 to at least 259 seats, and the exit poll figures are early^[2,11,12,13].

A change of chief of staff after electoral defeat

President Donald Trump announced on Friday 6 November 2026 that Stephen Miller, his deputy chief of staff and homeland security adviser, would become White House chief of staff in place of Susie Wiles^[1,2]. Miller is due to take up the post on Monday 9 November, and Wiles is moving to Trump's political operation^[1]. CBS News described the change as the most significant shake-up of Trump's team since the Republican losses in the midterm elections^[2].

CBS News reported that Wiles submitted a resignation on the Thursday evening and that people familiar with the decision linked it to the midterm defeats^[2]. Trump told reporters that Wiles had done "a very good job, great job" and called Miller "very good politically" and a "great manager"^[2,3,4]. Wiles was the first woman to serve as White House chief of staff^[1,3]. Fox News reported that the 21 months of Wiles in the post made the longest-serving of Trump's chiefs of staff across both terms^[5].

France 24 reported that, with Democrats now controlling both chambers of Congress, Trump was seeking a more aggressive approach to pushing Trump's agenda^[6].

Democratic gains and what voters said

CBS News reported that Democrats had secured at least 54 Senate seats, enough to control the chamber, with gains in Texas, Kansas, South Carolina, Ohio, Iowa, North Carolina and Maine, while the races in Mississippi and Alaska were still undecided^[7]. Estimates of the House majority differ by outlet and by the time of the count. CBS News projected between 251 and 268 of the 435 seats, NBC News estimated at least 259 with 21 races uncalled, Al Jazeera reported 253, and Fox News reported 228^[4,7,8,9,10].

Exit polls give the first systematic evidence of why voters chose as they did, though all are preliminary. The NBC News exit poll recorded Trump's approval at 38 per cent, against 45 per cent at the 2018 midterms, and found that 43 per cent of voters said they had voted to express opposition to Trump^[11]. The Fox News Voter Poll, which surveyed more than 100,000 voters between 19 October and 3 November, put approval at 38 per cent and disapproval at 62 per cent^[9].

The surveys point to several grievances at once. In the NBC poll, 57 per cent of voters said Trump's immigration enforcement had gone too far, 22 per cent said it was about right and 22 per cent said it had not gone far enough^[11]. The Fox poll found that Hispanic voters backed Democratic House candidates by 27 points, against a 12-point margin for Kamala Harris in 2024, that two-thirds blamed Trump's tariffs for harming the economy, and that 60 per cent thought military action against Iran was the wrong decision^[9]. CBS News reported that Vice-President JD Vance suggested the Iran war had contributed to Republican losses^[7].

Miller's record and the disputes surrounding it

Miller was born in 1985 and graduated from Duke University in 2007^[12]. From 2009 to 2016 Miller worked for Senator Jeff Sessions, concentrating on immigration, and joined Trump's campaign in January 2016 as a senior policy adviser^[12]. In the first administration Miller was senior adviser to the president for policy and director of speechwriting, and co-wrote Executive Order 13769, the first version of the 2017 travel restrictions, with Steve Bannon^[12]. These biographical details come from a compiled encyclopaedia entry rather than an official biography.

Sessions, by then attorney general, announced the zero tolerance policy for prosecuting illegal border crossers on 7 May 2018^[13]. On 14 January 2021 the Justice Department's inspector general reported that department leadership "failed to effectively prepare for and manage the policy's implementation", and that more than 3,000 children were separated from their parents before a presidential executive order of 20 June 2018 halted the practice^[14]. The report's findings were directed at Justice Department leadership^[13,14]. The Associated Press has described Miller as central to the separation programme^[15]. That description comes from journalism, not from the inspector general's report.

Euronews reported that the promotion of Miller comes amid heightened scrutiny of immigration enforcement after fatal shootings of protesters by immigration agents in Minneapolis in January 2026^[1]. Miller called Alex Pretti, a United States citizen shot dead by Border Patrol officers on 24 January, a "domestic terrorist", and PolitiFact concluded that video of the incident contradicted the officials' statements^[16]. That conclusion rests on journalists' reconstruction of video rather than on a completed official investigation.

Competing readings of the appointment

Euronews reported that Wiles had been widely regarded as an important organisational force who helped maintain discipline in the White House, and France 24 that some saw her as a stabilising force^[1,6]. Supporters present the appointment as a deliberate turn towards confrontation. Townhall, a conservative outlet, quoted unnamed sources describing Miller as a "wartime consigliere"^[17]. Fox News reported that the White House defended the record of Miller on border security, crime and deregulation, and that Vance called Miller an "amazing patriot"^[18].

Some Republicans in the House read the same facts as a refusal to learn from defeat. Representative Marlin Stutzman called the choice a "Horrible decision" and said that "we ruined a lot of our goodwill with Latino voters" because of the immigration positions of Miller^[18]. Representative Don Bacon said Miller "took an immigration policy that favored the president 2:1 in the public, over-reached and made it 2:1 unfavorable"^[18]. Bacon's ratio is a political judgement, but the NBC exit poll finding that 57 per cent of voters thought enforcement had gone too far points in the same direction^[11].

Democratic leaders were blunter still. Jeffries called Miller "a dangerous xenophobe and reckless extremist", and Schumer described Miller as "the architect of the most barbaric, inhumane policies"^[2,19]. NBC News interpreted the move as a decision to strengthen Trump's ties with the MAGA base for the final two years rather than to broaden Trump's appeal^[19]. CBS News judged that it signalled a hardline approach likely to make relations with the incoming Democratic leadership more confrontational^[2]. The Associated Press reported that Democrats are poised to investigate the administration and that Miller is a likely target^[3].

What remains uncertain

The link between the resignation and the midterm results comes from people familiar with the decision quoted by CBS News^[2], and the account of a deliberate shift to confrontation comes from anonymous insiders quoted by Townhall^[17]. Published estimates of the House majority range from 228 to at least 259 seats, and the Senate contests in Alaska and Mississippi were still being counted^[4,8,9]. The exit poll figures are early and subject to revision^[20]. How far immigration rather than the economy, tariffs or the Iran war drove the result is disputed, with Vance blaming the war and some Republican lawmakers Miller's immigration policy^[7,9,18]. Which further dismissals Trump intends remains unknown^[21].

Abstract

1A new chief of staff three days after the vote

President Donald Trump announced on Friday 6 November 2026 that Stephen Miller, his deputy chief of staff and homeland security adviser, would become White House chief of staff in place of Susie Wiles^[1,2]. Miller, who is 41, is due to take up the post on Monday 9 November, and Wiles, who is 69, is moving to Trump's political operation^[1]. Trump made the announcement on his Truth Social platform, calling Miller "one of my most trusted advisors"^[1]. CBS News described the change as the most significant shake-up of Trump's team since the Republican losses in the midterm elections^[2].

CBS News reported that Wiles submitted her resignation on the Thursday evening, that people familiar with the decision linked it to the midterm defeats, and that she had first intended to stay on through the lame-duck session of Congress before Trump brought her departure forward^[2]. Trump told reporters that he "wanted to make a change", adding that Wiles had done "a very good job, great job" and that "Stephen's been great"^[2,6]. He also called Miller "very good politically" and a "great manager"^[2,11]. Wiles said that serving Trump in the White House "has been the honor of a lifetime"^[1,6]. Fox News reported that she named "securing our border and cutting taxes" among the achievements of which she was proud^[14].

Wiles was the first woman to serve as White House chief of staff^[1,6]. Fox News reported that her 21 months in the post made her the longest-serving of Trump's chiefs of staff across both of his terms^[14]. The Associated Press described her successor as one of Trump's longest-serving advisers and as widely recognised as a chief architect of the administration's immigration policies^[6]. France 24 reported that, with Democrats now controlling both chambers of Congress, Trump was seeking a more aggressive approach to pushing his agenda^[15].

The timing drew attention because Trump had recorded an interview with Ross Douthat for the CBS programme 60 Minutes only hours before the announcement, for broadcast on the Sunday^[16]. Asked whether he expected to dismiss people, Trump replied "I do, a little bit", adding that he would "be doing maybe a few changes" but did not want to say who^[16]. In the same interview he said that he had confidence in the defence secretary, Pete Hegseth^[16].

2Democrats take both chambers and the polls explain why

The appointment follows a heavy Republican defeat. CBS News reported that Democrats had secured at least 54 Senate seats, enough to control the chamber, with gains in Texas, Kansas, South Carolina, Ohio, Iowa, North Carolina and Maine, while the races in Mississippi and Alaska were still undecided^[3]. NBC News reported that the Democrat Mary Peltola led the Republican senator Dan Sullivan in Alaska by about 600 votes, and that the Democrat Scott Colom led the Republican senator Cindy Hyde-Smith in Mississippi by about 2,500 votes^[11]. Al Jazeera put the Democratic gain in the Senate at seven seats^[10].

Estimates of the House majority differ by outlet and by the time of the count. CBS News projected that Democrats would hold between 251 and 268 of the 435 seats^[3,4]. NBC News estimated at least 259 Democratic seats with 21 races uncalled, Al Jazeera reported 253, and Fox News reported 228^[10,11,12]. The spread reflects the gap between projections of final outcomes and counts of races already called. CBS News reported that the House Democratic leader, Hakeem Jeffries, was expected to become the first Black Speaker, and that the Republican Speaker, Mike Johnson, would not run for minority leader^[4].

Exit polls give the first systematic evidence of why voters chose as they did, though all are preliminary. The CBS News exit poll interviewed thousands of voters at polling places on election day and in the weeks before it, and CBS noted that its results would be updated as votes were counted^[13]. On its early figures Trump's approval stood at 38 per cent, on track to be the lowest for a president at a midterm election^[13]. The NBC News exit poll also recorded 38 per cent, against 45 per cent at the 2018 midterms, and found that 43 per cent of voters said they had voted to express opposition to Trump^[5]. The Fox News Voter Poll, which surveyed more than 100,000 voters between 19 October and 3 November, put his approval at 38 per cent and disapproval at 62 per cent^[12].

The surveys point to several grievances at once. In the NBC poll, 57 per cent of voters said Trump's immigration enforcement had gone too far, 22 per cent said it was about right and 22 per cent said it had not gone far enough^[5]. The Fox poll found that Hispanic voters backed Democratic House candidates by 27 points, against a 12-point margin for Kamala Harris in 2024; that 75 per cent rated the economy negatively; that two-thirds blamed Trump's tariffs for harming the economy; and that 60 per cent thought military action against Iran was the wrong decision^[12]. CBS News reported that Vice-President JD Vance suggested the Iran war had contributed to Republican losses^[3].

3Fifteen years spent shaping immigration policy

Miller was born in Santa Monica, California, on 23 August 1985 and graduated from Duke University in 2007^[17]. He was press secretary to the Minnesota congresswoman Michele Bachmann and from 2009 to 2016 worked for Senator Jeff Sessions, where he concentrated on immigration and helped defeat the Border Security, Economic Opportunity, and Immigration Modernization Act of 2013^[17]. He joined Trump's campaign in January 2016 as a senior policy adviser, wrote the speech accepting the Republican nomination and later wrote the inaugural address^[17]. These biographical details come from a compiled encyclopaedia entry rather than an official biography.

In the first Trump administration Miller was senior adviser to the president for policy and director of speechwriting^[17]. He co-wrote Executive Order 13769, the first version of the 2017 travel restrictions, with Steve Bannon^[17]. On 26 June 2018 the Supreme Court, by five votes to four in Trump v. Hawaii, upheld a later version of the policy, Proclamation 9645, which restricted entry by nationals of eight countries; Chief Justice John Roberts wrote that the president had lawfully used his authority under the Immigration and Nationality Act^[18].

Sessions, by then attorney general, announced the zero tolerance policy for prosecuting illegal border crossers on 7 May 2018^[19]. On 14 January 2021 the Justice Department's inspector general reported that department leadership "failed to effectively prepare for and manage the policy's implementation", that Sessions and other officials understood it would separate families, and that more than 3,000 children were separated from their parents before a presidential executive order of 20 June 2018 halted the practice^[20]. According to notes cited in the report, Sessions told prosecutors "we need to take away children; if care about kids, don't bring them in"^[19]. The report's findings were directed at Justice Department leadership, particularly the attorney general's office^[19,20]. The Associated Press has described Miller as central to the separation programme^[21]. That description comes from journalism, not from the inspector general's report.

After 2021 Miller founded America First Legal, which the Associated Press described as a conservative counterpart to the American Civil Liberties Union^[17,21]. In November 2019 the Southern Poverty Law Center, an advocacy organisation, published its analysis of about 900 emails Miller exchanged with Breitbart News editors between March 2015 and June 2016, provided by the former Breitbart editor Katie McHugh^[22]. The centre said Miller had shared material from VDARE, which it calls a white nationalist website, and had recommended coverage of the novel The Camp of the Saints^[22]. Since 20 January 2025 he has been deputy chief of staff for policy and homeland security adviser^[17].

4Wiles and the memory of first-term turnover

Wiles came to the post after decades in Republican politics. The daughter of the American football player and broadcaster Pat Summerall, she worked in the Washington office of Representative Jack Kemp, was a scheduler on Ronald Reagan's campaign and White House staff, helped Rick Scott win the governorship of Florida and ran Trump's successful Florida campaign in 2016^[23]. She helped elect Ron DeSantis as governor of Florida and later ran Trump's 2024 primary campaign against him^[23]. When she was chosen in November 2024, PBS NewsHour reported Trump's description of the 2024 effort under her leadership as his "best-run campaign"^[23].

Her appointment invited comparison with Trump's first term, in which the post passed through Reince Priebus, John Kelly, Mick Mulvaney, who served as acting chief, and Mark Meadows^[23,24]. Kathryn Dunn Tenpas of the Brookings Institution, who tracked 65 senior posts in the Executive Office of the President, excluding Cabinet secretaries, found that 60 of them, or 92 per cent, had turned over by 20 January 2021^[24]. Her method draws on National Journal's directories of senior officials, supplemented by government websites, news reports and LinkedIn, and counts each post only once^[24]. Euronews reported that Wiles had been widely regarded as an important organisational force who helped maintain discipline in the White House, and France 24 that some saw her as a stabilising force^[1,15].

Her standing was tested in December 2025, when Vanity Fair published a profile by Chris Whipple based on 11 on-the-record interviews over the preceding year^[25]. In it Wiles described Trump as having "an alcoholic's personality" and called Vance a "conspiracy theorist"^[25]. On 17 December 2025 she called the profile a "disingenuously framed hit piece", while Whipple replied that "not a single fact in the piece has been contested"^[25]. Trump said he did have "an obsessive and addictive personality", although he does not drink^[25].

Reports of her departure recurred through 2026. In June the Daily Mail, citing five unnamed sources, reported that she planned to leave after the midterms, which she dismissed as a "piece of Friday fiction"^[26]. On 15 October Politico, citing four people, reported that Trump had discussed possible successors, including Steve Witkoff and Bill Pulte, with allies^[27]. Trump called the report "TOTAL FAKE NEWS" and said Wiles had his "COMPLETE confidence"^[27]. Fox News reported that she was diagnosed with early-stage breast cancer in 2025 and announced she was cancer-free by September 2026^[14]. NBC News noted that she is the seventh prominent woman to leave the administration in 2026, and that all the replacements so far have been men^[11].

5Minneapolis and the oversight to come

Euronews reported that Miller's promotion comes amid heightened scrutiny of immigration enforcement after fatal shootings of protesters by immigration agents in Minneapolis in January 2026^[1]. The most closely examined case is that of Alex Pretti, a 37-year-old United States citizen who worked as an intensive care nurse at the Minneapolis Veterans Affairs hospital and was shot dead by Border Patrol officers on 24 January^[28]. Miller called Pretti a "domestic terrorist" who "tried to assassinate federal law enforcement"^[28]. The homeland security secretary, Kristi Noem, said Pretti had "approached U.S. Border Patrol officers with a 9mm semi-automatic handgun"^[28].

The fact-checking organisation PolitiFact, drawing on video analyses by several news organisations, reported that the footage showed Pretti holding a mobile phone while standing between an officer and other civilians, being pepper-sprayed and tackled, and having a gun removed from his hip before another officer fired while he was restrained^[28]. PolitiFact concluded that the video contradicted the officials' statements^[28]. That conclusion rests on journalists' reconstruction of video rather than on a completed official investigation.

The case became the centre of a political dispute. On 29 January Jeffries called Miller "one of the malignant architects of the violence and brutality DHS has unleashed", Fox News reported^[29]. A White House spokeswoman, Abigail Jackson, replied that "Hakeem Jeffries is a buffoon who has repeatedly lied about and smeared federal law enforcement officers"^[29]. A senior Department of Homeland Security official said Miller "has been instrumental in delivering on the President's agenda" and credited him with helping achieve "the most secure border in American history"^[29].

The change in Congress gives these disputes an institutional outlet. The Associated Press reported that Democrats are poised to investigate the administration and that Miller himself is a likely target^[6]. Representative Robert Garcia warned that Democrats on the House oversight committee would investigate Miller once they take control in January, calling him "the architect" of the enforcement actions of Immigration and Customs Enforcement (ICE), Al Jazeera reported^[10]. The Senate Democratic leader, Chuck Schumer, said his party would "entangle" Trump "in legislative razor wire"^[3]. Defending Miller, the attorney general, Todd Blanche, said that "Stephen Miller has a lawyer" and that it was "the entire Department of Justice"^[11].

6Loyalty, defiance and rival readings of the choice

Miller's first public remarks centred on his loyalty to Trump. In a post on X he said it had been "the privilege of my lifetime to have served on his team from Day One", and at an event at Mar-a-Lago he said that "without President Trump, the United States of America would not exist right now"^[11]. NBC News reported that he pledged "absolute loyalty" and "total devotion" to Trump's success^[11]. Al Jazeera reported that he credited Trump with having "saved America"^[30].

Supporters present the appointment as a deliberate turn towards confrontation. Townhall, a conservative outlet, quoted unnamed sources describing Miller as a "wartime consigliere" and one insider saying that Trump had left "the denial stage" for a more defiant one^[7]. Townhall also quoted Karoline Leavitt, whom it described as a former press secretary, praising Miller as unmatched in loyalty, hard work and alignment with the America First movement^[7]. Fox News reported that the White House defended Miller's record on border security, crime and deregulation, and that Vance called him an "amazing patriot"^[8]. The health secretary, Robert F. Kennedy Jr., called him "the strongest MAHA supporter in the administration", referring to his Make America Healthy Again movement^[11].

Some Republicans in the House read the same facts as a refusal to learn from defeat. Representative Marlin Stutzman of Indiana called the choice a "Horrible decision" and said that "we ruined a lot of our goodwill with Latino voters" because of Miller's immigration positions^[8]. Representative Don Bacon of Nebraska said Miller "took an immigration policy that favored the president 2:1 in the public, over-reached and made it 2:1 unfavorable"^[8]. An unnamed Republican lawmaker called Miller "a megalomaniac who should have never been given the keys to the Ferrari"^[8]. Bacon's ratio is a political judgement, but the NBC exit poll finding that 57 per cent of voters thought enforcement had gone too far points in the same direction^[5].

Democratic leaders were blunter still. Jeffries called Miller "a dangerous xenophobe and reckless extremist", and Schumer described him as "the architect of the most barbaric, inhumane policies"^[2,9]. Schumer also said the appointment showed that Trump had "learned nothing from his historic defeat"^[9]. NBC News interpreted the move as a decision to strengthen Trump's ties with his MAGA base for his final two years rather than to broaden his appeal^[9]. CBS News judged that it signalled a hardline approach likely to make relations with the incoming Democratic leadership more confrontational^[2].

Uncertainties and open questions

Conclusion

The change replaces the first woman to serve as White House chief of staff, widely regarded as an organisational force who helped maintain discipline in the White House, with the adviser most closely identified with its immigration enforcement^[1,6]. It comes after voters gave Democrats control of both chambers of Congress, and as exit polls record majority disapproval of how that enforcement has been carried out^[3,5].

Trump and his allies point to Miller's loyalty and political skill as reasons for his promotion^[2,7,8]. Republican critics argue that his immigration policies contributed to the defeat, while Democratic leaders say that promoting him shows Trump has learned nothing from it^[8,9]. The evidence available so far cannot settle that argument. What it does show is that the next phase of the presidency will pit the White House against a Congress that has said it intends to investigate the new chief of staff himself^[6,10].
