Four days after Republicans lost control of Congress in the 2026 midterms, President Donald Trump reshuffled the top of his White House staff. On Friday, November 6, he announced that deputy chief of staff Stephen Miller will become chief of staff starting Monday, November 9, and that Susie Wiles will step down this week. This article sticks to reporting from NBC News and does not invent private conversations or unnamed Cabinet targets.

What Trump announced

According to NBC News, Trump wrote on Truth Social that he was “pleased to announce” Miller — currently deputy chief of staff and one of his “most trusted advisors” — would become chief of staff on Monday, November 9, 2026. Wiles, the first woman to serve as White House chief of staff and Trump’s longest-serving chief in that role, is leaving after the midterm rout.

Trump told reporters he “wanted to make a change,” praised Miller as “very good politically,” and said Wiles had “done a very good job,” NBC reported. Speaking later Friday, Trump said he expected “very little” additional Cabinet departures in the coming months, even as a CBS “60 Minutes” interview taped earlier and set to air Sunday showed him saying he might make “maybe a few changes.”

Who Stephen Miller is in this administration

Miller has been a central figure in Trump’s second-term immigration and homeland-security agenda, NBC noted. After the announcement, he posted that he was “honored beyond words,” thanked Wiles, and framed the mission as supporting the president. At a CPAC event at Mar-a-Lago on Friday night, NBC reported, Miller pledged “absolute loyalty” and said that without Trump “the United States of America would not exist right now.”

Democrats reacted sharply. House Democratic Leader Hakeem Jeffries called Miller “a dangerous xenophobe and reckless extremist” in a post quoted by NBC. Rep. Robert Garcia, expected to chair House Oversight, said Democrats would keep investigating Miller and told him to “lawyer up.” Attorney General Todd Blanche responded on Fox News that Miller already has a lawyer — “me” and the Justice Department — according to the same live blog.

Why the timing matters

The move lands in the middle of unfinished Senate counts in Alaska and Mississippi and with Democrats preparing to take over Congress. NBC’s Decision Desk estimated Democrats would control at least 259 House seats, with 21 races still uncalled late Friday. Against that backdrop, swapping the White House’s top manager signals how Trump wants to run the next two years of divided government.

NBC also noted that Wiles’ exit brings to seven the number of prominent women who have left the Trump administration this year, with most of those roles so far filled by men. Separately, former health adviser Calley Means criticized Wiles on Joe Rogan’s podcast shortly before her departure was announced, claiming she blocked parts of the “MAHA” agenda; the White House disputed that characterization and Health Secretary Robert F. Kennedy Jr. publicly thanked Wiles while calling Miller a strong MAHA supporter, NBC reported.

What to watch next

Miller starts Monday. Oversight Democrats have already named him as a target. Trump has publicly backed Defense Secretary Pete Hegseth even as some Republicans question the Iran war strategy. Those threads — staff loyalty, congressional investigations, and foreign policy — will define the first weeks of Miller’s tenure more than any single announcement.

The bottom line

The verified story as of Friday night is straightforward: Wiles is out, Miller is in on November 9, and both parties are already framing the change as either a show of strength or a provocation. Stick to the public statements and official reporting; the rest will play out in hearings and headlines next week.
