President Donald Trump announced Friday, November 6, 2026, that Stephen Miller will become his new White House chief of staff, replacing Susie Wiles after Republicans suffered major losses in the midterm elections. Miller, one of Trump's closest advisers and a leading figure behind his immigration policies, will officially begin his new position on Monday, November 9.
The appointment represents a significant change in White House leadership as Trump prepares to work with a Democratic-controlled Congress during the final two years of his presidency. Wiles, who made history as the first woman to serve as White House chief of staff, will move into a role with Trump's political organization.
Trump praised both officials while announcing the transition on Truth Social. He described Miller as one of his most trusted advisers and thanked Wiles for her work managing the administration.
Trump Promotes a Longtime Political Adviser
Miller, 41, has worked closely with Trump since the 2016 presidential campaign. He served as a senior policy adviser and speechwriter during Trump's first administration before returning to the White House in 2025 as deputy chief of staff for policy.
His responsibilities during Trump's second term have included immigration enforcement, homeland security and coordination of major domestic policy initiatives. He has become one of the administration's most influential voices on border security and the use of executive authority.
The president confirmed the appointment through a public statement, making Miller the 33rd White House chief of staff. The White House subsequently published an announcement featuring messages of support from Cabinet officials, Republican lawmakers and conservative organizations.
Vice President JD Vance congratulated Miller and thanked Wiles for her service. Secretary of State Marco Rubio also praised Wiles while expressing confidence that Miller would help advance the administration's agenda.
Speaking to reporters Friday, Trump said he wanted to make a leadership change and emphasized that he remained satisfied with Wiles' performance. He did not describe the appointment as a direct response to the midterm election results.
The timing nevertheless places Miller at the center of an administration facing substantial political challenges. Democrats won control of both chambers of Congress in Tuesday's elections, changing the balance of power in Washington.
Susie Wiles Leaves After Historic Tenure
Wiles, 69, became White House chief of staff when Trump began his second presidential term in January 2025. She previously helped manage his successful 2024 presidential campaign and played an important role in organizing his political operation.
She was widely credited with bringing greater structure to Trump's staff and coordinating communication among senior administration officials. Her responsibilities included managing access to the president, overseeing White House operations and helping resolve disagreements among advisers.
Wiles submitted her resignation Thursday, one day before Trump publicly announced her replacement. Her departure follows a period of considerable political pressure on the administration.
In a farewell statement, Wiles described her service as the honor of a lifetime. She expressed pride in the administration's work on border security, economic policy and other priorities while confirming that she would remain involved with Trump's political organization.
Her next responsibilities have not been fully detailed. However, Trump said she would move to his political operation rather than leave his broader team entirely.
Wiles' departure also follows her treatment for breast cancer earlier this year. She announced in September that medical testing showed she was cancer-free, although there is no confirmed evidence that her health was the reason for the leadership change.
The decision ends a tenure during which Wiles became one of the president's most prominent advisers. Her successor brings a different professional background, having concentrated more heavily on policy development and enforcement priorities.
Immigration Policies Remain Central to Miller's Influence
Miller has been a leading advocate of Trump's restrictive immigration agenda for nearly a decade. During the president's first administration, he helped develop policies intended to reduce unauthorized immigration and tighten admission requirements.
His influence expanded during Trump's second term as the administration pursued increased deportations, workplace enforcement and restrictions on immigration programs.
Miller has supported ambitious enforcement targets and argued that federal agencies should use their existing authority more aggressively. Supporters credit those efforts with strengthening border security and enforcing immigration laws.
Critics argue that the policies have threatened civil liberties, disrupted families and placed excessive pressure on immigrant communities. Several enforcement measures have faced challenges in federal courts, reflecting disagreements over their legal authority and implementation.
Immigration enforcement was also a major issue during the 2026 midterm campaign. Polling reported by the Associated Press indicated that roughly six in ten voters believed the administration's immigration enforcement efforts had gone too far.
The administration's handling of immigration operations received additional scrutiny after federal agents fatally shot two people during separate encounters in Minneapolis in January. The incidents triggered protests and disputes over the use of force by federal officers.
Miller defended the administration's enforcement priorities during that period. His promotion suggests that immigration will remain prominent within White House decision-making, although the administration has not announced a new policy package accompanying his appointment.
Democrats Condemn the Appointment
Democratic leaders responded sharply to Miller's promotion, arguing that Trump had failed to recognize the political message delivered by voters in the midterm elections.
Senate Democratic leader Chuck Schumer called Miller a central architect of the administration's most controversial policies. He argued that elevating Miller demonstrated Trump's unwillingness to change direction following Republican losses.
House Democratic leader Hakeem Jeffries also condemned the appointment. He characterized Miller as an extremist and called for his removal from government rather than his promotion.
Representative Robert Garcia, who is expected to lead the House Oversight Committee when Democrats assume control in January, said lawmakers would continue investigating Miller's conduct and the administration's immigration policies.
These statements reflect the growing confrontation between the White House and congressional Democrats. With their new majorities, Democrats will have greater authority to schedule hearings, request records and investigate executive branch activities.
Congressional oversight could become particularly important in examining immigration operations, federal spending and actions taken by agencies implementing presidential directives.
Republican responses have been more mixed. Many prominent party officials welcomed Miller's appointment, citing his loyalty and experience within the administration.
Others questioned whether elevating such a divisive figure would help Trump work with the incoming Democratic majorities. Republican Senator Thom Tillis criticized the choice, arguing that the president needed a more effective approach to negotiations following the election losses.
A Powerful Position Inside the White House
The White House chief of staff is one of the most influential positions in the executive branch. Although the role does not require Senate confirmation, the person holding it often determines which advisers meet with the president and how major policy decisions move forward.
The chief of staff also coordinates the administration's legislative strategy and helps manage relationships with congressional leaders. Those responsibilities become especially important when the president's party does not control Congress.
Miller's appointment could therefore influence more than immigration policy. He will now oversee the broader White House staff while helping coordinate responses to legislative proposals, investigations and political disputes.
His previous experience gives him familiarity with the federal agencies and officials responsible for implementing Trump's agenda. However, managing the entire White House operation will require balancing competing priorities beyond his previous policy portfolio.
The transition also creates questions about how the administration will approach negotiations with Democratic lawmakers. Trump has said he wants to work with the incoming congressional leadership on certain matters, although significant disagreements remain over immigration, spending and executive power.
Miller's longstanding positions suggest that major compromises on immigration could be difficult. Still, the specific direction of negotiations will depend on decisions made by Trump and congressional leaders rather than the chief of staff alone.
White House Faces a Changed Political Landscape
The appointment comes three days after the November 3 midterm elections, which substantially weakened Republican control in Washington. Democrats gained congressional seats and will enter the next legislative session with new authority to challenge the administration's policies.
Trump faces the possibility of more frequent investigations and tighter legislative constraints during the remainder of his presidency. The administration may also need to rely more heavily on executive actions when its proposals cannot secure support in Congress.
For Miller, the promotion represents the highest-ranking White House position of his political career. His responsibilities will extend across the administration while he continues working closely with a president who has relied on his advice for a decade.
Wiles is expected to remain connected to Trump's political organization, maintaining a relationship that began long before his return to the White House.
Miller is scheduled to take office Monday, November 9. His first major challenge will be organizing the White House response to the election results and preparing the administration for a newly empowered Democratic Congress in January 2027.
