President Donald Trump has named Stephen Miller his new White House chief of staff, calling him one of his “most trusted advisors.”
Miller will ascend to the role on Monday, officially replacing Susie Wiles, who Trump said will be moving to his political operation.
“I want to thank her for her service as Chief of Staff — She has done a great job!” Trump wrote.
Moments after Trump’s announcement, Wiles issued a statement of her own.

“Today is my last day as White House Chief of Staff,” Wiles said.
“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,” she added. “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.”
The announcement came after Republicans lost control of both the House and Senate in the midterm elections, dealing a major blow to President Donald Trump after the war with Iran and persistent affordability concerns loomed large over elections, as voters weighed the economic toll of the conflict.
A current White House official told Fox News Digital the decision was “very amicable” and Wiles handed her resignation in Thursday night.

Wiles worked on Trump’s 2016 and 2020 campaigns, making history as the first woman to serve as chief of staff. She is a longtime Trump ally, first throwing her support behind him in 2015 when she became the Trump campaign’s co-chairwoman in Florida.
“As a card-carrying member of the G.O.P. establishment, many thought my full-throated endorsement of the Trump candidacy was ill-advised — even crazy,” Wiles told the New York Times in a rare public statement back in 2016.
Wiles has served in her role for 21 months, making her Trump’s longest-serving chief of staff across both of his terms. Trump cycled through four chiefs of staff during his first term, with John Kelly serving the longest—about 17 months.
She has been dubbed the “Ice Maiden” by Trump, which he noted in his 2024 victory speech, for hard-nosed approach to handling business.
Wiles was seen as Trump’s behind-the-scenes, sitting in on high-level meetings and standing by his side at events, but Wiles rarely spoke directly to the public.
In March, Wiles announced she had been diagnosed with early-stage breast cancer upon early detection and received a strong prognosis. Six months later in September, she shared she was cancer free.

“With grit, determination, faith and the support of extraordinary people, it is possible to fight this disease while continuing to embrace the work, relationships and sense of purpose that make you who you are,” Wile wrote in a USA Today op-ed in September. “For me, that means serving my president and my country. I will always be grateful to President Donald Trump for the kindness and compassion while I was undergoing treatment.”
