Washington — Trump Names Stephen Miller White House Chief of Staff

President Donald Trump announced Friday afternoon that Stephen Miller, his deputy chief of staff and the architect of his immigration crackdown, will take over as White House chief of staff, replacing Susie Wiles, according to The Guardian. The move puts one of the administration's most controversial aides in charge of the president's daily schedule, staff and policy flow, starting immediately.

What did Trump announce, and when?

Trump posted the news on his Truth Social platform Friday afternoon, confirming that Wiles had been removed from the top staff job and that Miller would take her place, the Guardian reported. The announcement came without advance notice to the public and arrived just days after the November midterm elections, in which Democrats won control of Congress away from Trump's Republican Party, according to the Guardian.

Who is Stephen Miller, and what will he do as chief of staff?

Miller has served as Trump's deputy chief of staff and is described by the Guardian as the architect of the administration's sweeping immigration crackdown. He co-authored the conservative policy blueprint known as Project 2025 and has pushed for ending birthright citizenship, the Guardian reported. He has also raised the idea that the United States could move to acquire Greenland, according to the outlet. As chief of staff, Miller now controls who sees the president, how policy moves through the West Wing, and how the administration executes its agenda for the remainder of the term.

How are Democrats reacting to the appointment?

Democratic lawmakers moved quickly to condemn the choice. Senator Dick Durbin of Illinois wrote on X that "for Trump to promote this hatemonger shows he has learned nothing," the Guardian reported. Senate Democratic leader Chuck Schumer said Trump "learned nothing from his historic defeat" and "couldn't have made a worse choice" in elevating Miller, according to the Guardian.

House Democratic leader Hakeem Jeffries, who is expected to become the chamber's first Black speaker, called Miller "a dangerous xenophobe and reckless extremist who has American blood on his hands" and demanded he be removed from the post, the Guardian reported. Senator Chris Van Hollen of Maryland described the move as "another kick in the teeth to the American people" and "a sign of Trump's contempt for the voters," according to the outlet.

The Guardian's headline cites both Democrats and Republicans criticizing the pick as "dangerous," though the specific Republican objections were not detailed in the available reporting.

What happened to Susie Wiles?

Trump confirmed in his Friday post that Wiles had been ousted from the chief of staff role, the Guardian reported. The outlet's reporting did not include a stated reason for her removal or further comment from Wiles herself.

Key dates

• May 30, 2026: Miller appears on CNN discussing administration policy, per a photo caption cited by the Guardian.
• Early November 2026: Democrats win control of Congress in the midterm elections, ending Republican control, according to the Guardian.
• Friday, Nov. 6-7, 2026: Trump announces via Truth Social that Miller will replace Wiles as chief of staff, the Guardian reported.

What changes starting Monday?

With Miller now running the West Wing, aides, lawmakers and reporters who deal with the White House will be working through a new gatekeeper. Miller's record as an immigration hardliner means agencies tied to enforcement and border policy are likely to see continued attention from the top of the staff, based on his role described by the Guardian as the architect of the crackdown. Congressional Democrats who will soon control both chambers have signaled they intend to use oversight and floor speeches to challenge the appointment, judging by the public statements from Durbin, Schumer, Jeffries and Van Hollen cited by the Guardian. No timeline for Senate confirmation applies, since chief of staff is not a Senate-confirmed position, but the political fight over Miller's influence is expected to continue as the new Congress organizes.

The Guardian's report did not include comment from the White House beyond Trump's social media post, nor did it include a statement from Miller himself responding to the criticism.
