Stephen Miller will replace Susie Wiles as White House chief of staff starting Monday, President Donald Trump announced on Truth Social Friday afternoon. Wiles will take on a role within Trump’s political operation.

Miller has played an influential role in Trump’s first and second administrations. As a policy and Homeland Security adviser, Miller is widely credited with shaping Trump’s immigration agenda, including selecting enforcement targets.

News of the swap comes three days after Republicans took massive losses in the midterm elections, handing Democrats a majority in both the House and the Senate.

On his way out of the White House on Friday afternoon, Trump told reporters he “wanted to make a change” regarding his chief of staff. “I think Susie’s done a very good job — great job — but I just wanted to make a– Stephen’s been great. And we gotta make moves. Sometimes in life, you have to make moves,” he said. The New York Times has reported that Trump blames Wiles for the devastating midterm results.

Miller’s pitch for the position was reportedly to ease out of the war in Iran, a move that voters appear overwhelmingly in favor of. However, midterm exit polls also suggest that a substantial number of voters disapprove of Trump’s immigration policies. That dissatisfaction was reflected at the ballot box, with every House district along the southern border with Mexico turning blue.

Many of these voters have criticized the administration’s aggressive deportation policy, of which Miller was the chief architect. Miller pushed for DHS and ICE to dramatically increase arrests, setting a goal of 3,000 per day — roughly triple the rate proposed early in Trump’s second term. By early 2026, a majority of the individuals targeted and detained by law enforcement had no criminal records or violent histories. In interviews leading up to and following the election, voters cited the deportation of friends and family as a source of frustration.

Wiles shared the news of her departure in a post on X, saying Friday would be her last day as chief of staff. “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.”

Members of Trump’s cabinet responded positively to Miller’s promotion. Vice President JD Vance thanked Wiles for her service and added, “Stephen Miller is an amazing patriot and will do great things. Congrats to him on a well deserved promotion!” Defense Secretary Pete Hegseth posted his own congratulations to Miller, describing him as a “a true patriot and America First fighter.” Secretary of State Marco Rubio, Interior Secretary Doug Burgum, Attorney General Todd Blanche, and others tacked on their congratulations and support for Miller in his new position.

“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! President DONALD J. TRUMP,” Trump wrote on Truth Social.
