United States President Donald Trump has appointed his longtime aide and immigration policy architect, Stephen Miller, as his new White House chief of staff, following the Republican Party’s major losses in the midterm elections.
Miller, 41, will take over from Susie Wiles on Monday, November 9, with Trump announcing the appointment on his Truth Social platform on Friday.
Trump described Miller, who currently serves as Deputy Chief of Staff and Homeland Security Adviser, as one of his most trusted advisers.Â
He also praised Wiles for her work and said she would move to the Trump political operation.
“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,” Trump wrote.
“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 among Trump’s closest advisers for more than a decade and is a key figure behind the administration’s restrictive immigration policies.
He has played a central role in implementing the president’s mass deportation programme, which has involved raids by immigration agents across the country.
His approach to immigration has attracted widespread criticism, particularly following the fatal shootings of two demonstrators by immigration agents in Minneapolis in January. The incidents triggered large demonstrations.
The appointment comes after the White House repeatedly dismissed reports that Wiles, the first woman to serve as a US presidential chief of staff, was facing dismissal.
However, Miller’s elevation signals Trump’s intention to maintain his policy direction following the Republicans’ sweeping midterm defeat, which cost the party control of both chambers of Congress.
Wiles, 69, recently announced that she had been cleared of breast cancer. In a statement posted on X, she confirmed that Friday would be her final day as chief of staff.
Today is my last day as White House Chief of Staff.
Serving President Trump in the White House has been the honor of a lifetime. I’m so proud to have been a part of what we’ve accomplished together from securing our border and cutting taxes to strengthening our economy and putting America First.
More than anything, I’m grateful for the extraordinary people I’ve had the privilege of working alongside. While my role may be changing, my commitment to the President and the mission never will.

She described her time serving in the White House as a significant honour and expressed pride in the administration’s record, highlighting its efforts to secure the US border, reduce taxes, strengthen the economy and promote Trump’s America First agenda.
“Serving President Trump in the White House has been the honor of a lifetime,” she wrote.
“I’m so proud to have been a part of what we’ve accomplished together from securing our border and cutting taxes to strengthening our economy and putting America First.”
