Stephen Miller Named White House Chief of Staff as Democrats Gain Congress

Stephen Miller will take over as White House chief of staff on Monday, a move that consolidates the influence of one of President Donald Trump’s closest aides over the executive branch. The appointment was announced on Friday, replacing Susie Wiles in the role that controls access to the president and manages the daily operations of the West Wing.

Miller, 41, has been a central figure in the administration’s immigration strategy since January 2025. As deputy chief of staff for policy and homeland security adviser, he helped orchestrate a mass deportation campaign that saw immigration agents target communities across the United States. In May 2025, Miller told Fox News that the administration aimed for at least 3,000 arrests by Immigration and Customs Enforcement every day, with Trump pushing to raise that number further.

The promotion comes at a moment of political tension. Earlier this week, Republicans suffered a heavy defeat in the midterm elections. Democrats will control both the House of Representatives and the Senate starting in January. Lawmakers from the opposing party are expected to open investigations into Miller’s tenure, citing his history of controversial policy positions and public remarks.

Miller’s path to the top of the White House staff began in 2016 when he joined Trump’s initial presidential campaign. He served as a speechwriter and adviser during the president’s first term, where he helped shape messaging on immigration. He is credited with influencing the Department of Justice’s 2018 Zero Tolerance policy, which led to the separation of families at the southern border. Trump later modified that policy via executive order following public outcry.

During that first term, Miller also advocated for ending the Deferred Action for Childhood Arrivals program and supported the 2017 travel ban on several Muslim-majority countries. The initial order blocked citizens of Syria, Iran, Iraq, Libya, Somalia, Sudan, and Yemen from entering the United States for 90 days. The Supreme Court eventually upheld an adjusted version of the policy.

Miller’s stance on immigration has often drawn criticism from Democrats. In 2020, Representative Joaquin Castro stated that it was unacceptable for the administration to place a known supporter of white nationalist ideologies in a position of power. That statement followed a 2019 release of emails by the Southern Poverty Law Center that appeared to show Miller supporting such websites.

Since returning to the White House in 2025, Miller has defended aggressive tactics by immigration enforcement agents. He initially described Renee Good and Alex Pretti, who were killed by agents in Minneapolis in January, as terrorists. He later walked back his comment regarding Pretti. Miller has also been a vocal supporter of Trump’s military actions in the Western Hemisphere, including the abduction of Venezuelan leader Nicolas Maduro.

The chief of staff role is often described as a gatekeeper to the presidency. The position involves overseeing White House staff, managing hiring, maintaining the president’s calendar, and advising on policy. It remains unclear how Miller’s new title will alter his direct influence over Trump’s decision-making, particularly regarding border enforcement and international affairs.

Former adviser Steve Bannon told the Associated Press in 2017 that Miller helped Trump find his voice early in their relationship. Trump called Miller one of his most trusted advisors in a post on Truth Social announcing the change.

Miller’s background includes work as a legislative aide to Republican members of Congress and Senator Jeff Sessions in Washington, D.C. Before that, he led the conservative union at Duke University and worked on local radio shows in Santa Monica, California, where he criticized school policies.
