Trump names Stephen Miller his next chief of staff after major Republican midterm losses

WASHINGTON (AP) — President Donald Trump said Friday that Stephen Miller was replacing Susie Wiles as White House chief of staff, mere days after Republicans lost control of Congress in the midterm elections.

On his social media site, Trump praised Wiles and said she'd continue to work for his political organization. Wiles also released a social media statement Friday.

"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," Wiles said in a social media post shortly after Trump's announcement. She added that her commitment to "the President and the mission" will not change.

Miller, long a key member of Trump's inner circle, is a key architect of the administration's hard-line immigration policies.

Wiles, the steely political operator and longtime adviser to Trump, was the first woman to ever serve in that post.

Wiles' departure comes almost immediately after the GOP's midterm thrashing on Tuesday. She will be replaced by Stephen Miller, a longtime trusted aide to Trump.

The departure also came months after Wiles indicated she no longer showed evidence of breast cancer after she underwent months of treatment for the disease, a diagnosis she went public with in March 2026.

Wiles is the longest-serving White House chief of staff for Trump, who cycled through four of them during his first four-year term.

Miller is one of Trump's closest and longest-serving advisers, jumping on board during his longshot 2016 presidential campaign as a speechwriter. He currently serves as White House deputy chief of staff, and though he has a wide-ranging portfolio, Miller is most closely aligned with Trump's immigration policy and rhetoric on immigration.

Miller is a former aide to hardliner former Sen. Jeff Sessions, R-Ala., who would go on to serve as Trump's first attorney general.
