Donald Trump has appointed longtime adviser Stephen Miller as his new White House chief of staff, choosing a hard-line political ally after his Republican Party suffered major losses in the midterm elections. The move has raised questions about whether the president plans to work with Democrats or prepare for a fresh political fight.
Trump announced the decision on Friday through his Truth Social account. Miller will replace Susie Wiles, who helped manage Trump’s successful 2024 presidential campaign and served as a key figure in his second administration.
The appointment came just days after Republicans faced a sweeping defeat in Tuesday’s midterm elections. Trump had said he was ready to work with Democrats who gained strength in Congress. However, choosing Miller for one of the most powerful jobs in the White House may point to a more confrontational approach.
Miller welcomed the decision in a post on X. He said he was deeply honored to receive the president’s trust. He also called on supporters to fight with full commitment to support Trump and defend the country.
Trump praised Miller while speaking to reporters after making the announcement. He said Miller had been with him from the start of his political career and understood his goals. The president’s comments showed the level of trust he places in the adviser.
The White House chief of staff plays a central role in running the administration. The person controls access to the president, helps set policy priorities and manages daily operations. The job also involves talks with lawmakers, political groups and other key figures outside the White House.
Miller is widely known for shaping Trump’s strict immigration policies. He has been a leading voice behind efforts to expand deportations and increase federal funding for immigration enforcement across the United States.
His role in these policies has made him a major target of criticism from immigration rights groups and political opponents. Miller has often defended tough enforcement measures as necessary to protect national security and uphold federal law.
He also faced strong criticism after the killing of Alex Pretti during a major immigration operation in Minneapolis. Pretti was shot and killed by federal immigration officials. Miller initially described him as a domestic terrorist and an assassin. He later softened his comments, saying federal agents may not have followed the proper rules.
Miller has also reportedly played a major role in shaping US military actions in Venezuela and operations targeting suspected drug trafficking groups in the Caribbean and eastern Pacific. Critics have questioned the legality of some of these actions and described the deaths linked to them as unlawful killings.
His relationship with Trump dates back to the 2016 presidential campaign. Miller joined the campaign early as a political strategist. He also became known for delivering aggressive speeches before Trump’s rallies, where he often attacked the president’s political opponents.
Unlike many senior officials from Trump’s first administration, Miller remained close to the president throughout his first term. He continued to support Trump after the 2020 election, when the president refused to accept his defeat and efforts to challenge the result failed.
Miller returned to the White House during Trump’s second term as deputy chief of staff for policy. His new appointment gives him an even stronger position in the administration and greater influence over the president’s daily agenda.
Wiles, by contrast, had built a reputation for a calmer management style. She helped lead Trump’s 2024 campaign and was seen as a steady figure inside the White House. Her approach was different from the frequent staff changes and internal disputes that marked Trump’s first term.
However, Trump’s confidence in Wiles reportedly weakened in recent months as his political standing fell. The Republican defeat in the midterms appears to have added to the pressure on her position.
Reports also suggested that Trump was unhappy with stories claiming people close to Wiles were receiving profitable consulting work through their links to the president.
Miller’s promotion now signals a major change in the White House leadership. His close ties to Trump and strong political views could shape how the administration responds to the new balance of power in Congress. With Democrats gaining influence, the president may face greater pressure to negotiate, but Miller’s appointment could point to a tougher political strategy.
