Trump Names Stephen Miller Chief of Staff, Replacing Susie Wiles

President Donald Trump on Friday named deputy chief of staff for policy Stephen Miller as his new White House chief of staff, calling him one of his "most trusted advisors." Miller starts Monday.

Susie Wiles, who has held the job for 21 months, is moving to Trump's political operation. "I want to thank her for her service as Chief of Staff — She has done a great job!" Trump wrote. Wiles said in her own statement: "Today is my last day as White House Chief of Staff," calling the post "the honor of a lifetime." A White House official described the transition as "very amicable" and said Wiles submitted her resignation Thursday night.

Wiles was the first woman to serve as Trump's chief of staff, and her 21 months is the longest tenure of any Trump chief across both terms. John Kelly lasted about 17 months in the first term.

The shake-up comes days after Republicans lost control of both the House and the Senate in Tuesday's midterms. Fox News tied the losses to the Iran war and persistent affordability concerns.

Allies rallied behind the pick. Vice President JD Vance thanked Wiles for her "friendship and service" and called Miller "an amazing patriot." Communications director Steven Cheung called Miller "a Trump OG" and the president's strongest advocate for his agenda. Attorney General Todd Blanche said he looks forward to working with him.

The message is hard to miss: after a rough night, the president is putting his most committed policy architect in the building's top staff job, not trimming the agenda. One administration official called Miller "a great pick" who has the trust of millions of Americans on reversing mass migration.
