United States President Donald Trump has appointed Stephen Miller, one of his closest advisers and the architect of his hardline immigration policies, as his new White House Chief of Staff.
Trump announced the appointment on Friday through his Truth Social platform, saying Miller, the current Deputy Chief of Staff, would assume the position on Monday, November 9, 2026.
Miller will succeed Susie Wiles, who is leaving the position to take up a role in the President’s political operation.
Announcing the decision, Trump described Miller as one of his most trusted advisers and praised Wiles for her performance as chief of staff.
He wrote, “I am pleased to announce that Mr. Stephen Miller, the current Deputy Chief of Staff of the Trump Administration, and one of my most trusted advisors, will become the Chief of Staff starting Monday, November 9, 2026.
“Susie Wiles, who has done an outstanding job, will be moving over to the Trump Political Operation. I want to thank her for her service as Chief of Staff — she has done a great job!”
Miller has been a close ally of Trump since his 2016 presidential campaign, when he served as a speechwriter.
He subsequently became a senior policy adviser during Trump’s first administration, playing a central role in developing and implementing the President’s immigration agenda.
He returned to the White House in January 2025 as Deputy Chief of Staff for Policy and Homeland Security Adviser, emerging as one of the administration’s most influential figures on immigration and domestic policy.
During Trump’s first term, Miller helped shape several controversial immigration measures, including the 2018 family separation policy, which resulted in thousands of migrant children being separated from their parents at the US-Mexico border.
Wiles, a veteran political strategist, made history as the first woman to serve as White House Chief of Staff when Trump appointed her at the beginning of his second term in January 2025.
She previously helped manage Trump’s 2016 and 2020 presidential campaigns in Florida and oversaw his successful 2024 presidential campaign. She was widely credited with bringing greater discipline and coordination to his campaign operations.
The leadership change comes days after the Republican Party lost control of both chambers of Congress in the November 3 midterm elections, with Democrats securing majorities in the House of Representatives and the Senate.
The results are expected to give Democrats greater powers to scrutinise the Trump administration, challenge its policies and block parts of its legislative agenda during the final two years of his presidency.
