Donald Trump has announced that White House Chief of Staff Susie Wiles will leave the role and be replaced by his senior adviser, Stephen Miller.
“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 advisers, will become Chief of Staff starting Monday, November 9, 2026,” Trump wrote on Truth Social.
Trump said Wiles, who he credited with doing “an outstanding job,” would move to the Trump Political Operation. “I want to thank her for her service as Chief of Staff — she has done a great job!” he added.
The unexpected announcement came Friday afternoon, only days after Democrats delivered a sweeping election victory that dealt Trump and Republicans a major political setback.
The scale of the Democratic gains could keep Republicans from reclaiming a congressional majority for much of the next decade—a painful prospect for conservatives who had urged Trump to overhaul his team.
A senior White House official told the Daily Mail that Wiles “gave her resignation last night.”
“Today is my last day as White House Chief of Staff,” Wiles wrote on X. “Serving President Trump in the White House has been the honor of a lifetime.”
“I’m so proud to have been 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.”

Her departure follows a Daily Mail report published in June that said Wiles planned to step down after the midterm elections.
Although she denied the report at the time, Wiles ultimately exited just days after the election results were announced.
Wiles was the longest-serving Republican White House chief of staff and had been part of Trump’s political orbit since his 2016 campaign.

The Florida political strategist initially earned praise for bringing a calm, disciplined presence to the president’s often unpredictable West Wing. Trump and his aides began referring to her as the “ICE Queen.”
As the administration progressed and controversies mounted—from Elon Musk’s aggressive effort to reduce government spending to the handling of the Iran war—Wiles increasingly became a prominent figure in media coverage.
Late last year, a revealing interview with Vanity Fair included sharp assessments of several of the most influential figures in Trump’s Cabinet.
Wiles reportedly said Trump had “an alcoholic’s personality,” described Vice President JD Vance as a “conspiracy theorist for a decade,” and accused former Attorney General Pam Bondi of having “whiffed” on the release of the Jeffrey Epstein files.
“Very grateful to Susie for her friendship and service to the president and our country,” Vance wrote Friday. “Stephen Miller is an amazing patriot and will do great things. Congrats to him on a well-deserved promotion!”

“Patriots in control,” Hegseth wrote on X shortly after Wiles announced her resignation. He did not mention Wiles and instead praised Stephen Miller
As recently as September, one source said Wiles had been telling people directly that Republicans would win the midterm elections.
After the party’s election defeat, however, Trump began searching for someone to hold responsible, insiders told the Daily Mail.
According to those sources, Trump contacted advisers to discuss Secretary of War Pete Hegseth and his performance—an indication to some that the Pentagon chief could be vulnerable.
Wiles’ exit and Miller’s promotion may give Hegseth greater security for now, given his close ties to Trump’s longtime senior adviser.
“Patriots in control,” Hegseth posted on X just minutes after Wiles announced her resignation.
“Huge CONGRATS to [Miller]—a true patriot and America First fighter. He never backs down—and the [Department of War] is right there with him,” the secretary wrote in a second post. He did not publish any statement about Wiles.
