US President Donald Trump has appointed his Deputy Chief of Staff, Stephen Miller, to become the next White House Chief of Staff, marking a change in the leadership of his administration.

Miller is expected to assume the position on Monday, November 9, 2026, while outgoing Chief of Staff Susie Wiles will move to Trump’s political operation.

Trump announced the appointment on Friday, November 6, through his Truth Social platform, describing Miller as one of his most trusted advisers and commending Wiles for her service.

Trump Confirms Miller’s Appointment

In announcing the decision, Trump highlighted Miller’s current position in the administration and confirmed when the new appointment would take effect.

The US president wrote:

“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 advisors, will become the Chief of Staff starting Monday, November 9, 2026.”

Trump also confirmed that Wiles would be moving to his political operation, while expressing appreciation for her contribution to the administration.

He added:

“Susie Wiles, who has done an outstanding job, will be moving over to the Trump Political Operation. I want to thank her for her service as Chief of Staff, she has done a great job!”

The announcement places Miller in a position of greater responsibility within the White House, while Wiles is set to continue her involvement in Trump’s political activities.

Who Is Stephen Miller? A Look At His Political Background

Miller has been associated with Trump since the 2016 presidential campaign, when he worked as a speechwriter and helped shape the president’s political messaging.

During Trump’s first administration, he served as a senior policy adviser and became an influential figure in developing the administration’s immigration agenda.

His work included helping formulate the hardline immigration policies introduced during Trump’s first term, including the 2018 policy that resulted in the separation of thousands of migrant families at the US-Mexico border.

Miller returned to the White House in January 2025 as Deputy Chief of Staff for Policy and Homeland Security Adviser.

In those roles, he became one of the administration’s central figures on immigration and domestic policy. His appointment as Chief of Staff now gives him responsibility for a broader leadership position within the White House.

Susie Wiles’ Departure Marks A Change In White House Leadership

Wiles became the first woman to serve as White House Chief of Staff when she assumed the position in January 2025.

The veteran political strategist had built a longstanding working relationship with Trump through his presidential campaigns.

She played important roles in managing his 2016 and 2020 campaign operations in Florida before helping oversee his successful 2024 presidential campaign.

Wiles was also credited with bringing greater organisational discipline to Trump’s campaign operations.

Her move to the Trump Political Operation means she will leave the White House Chief of Staff position but remain connected to the president’s political activities.

Appointment Comes After Republican Midterm Losses

The leadership change comes days after the November 3, 2026, midterm elections, in which the Republican Party reportedly lost control of both chambers of Congress to the Democrats.

The reported results leave the Democrats with majorities in the House of Representatives and the Senate, creating a new political situation for the Trump administration.

Against this background, Miller’s appointment represents an important development in the White House leadership structure as the administration prepares for the next phase of its political and legislative activities.

However, the announcement did not provide further details about the specific responsibilities Wiles will assume in Trump’s political operation.

What Happens Next?

According to Trump’s announcement, Miller will officially take over as White House Chief of Staff on Monday, November 9, 2026.

Wiles is expected to move to the president’s political operation, although further details about her responsibilities have not been provided in the announcement.

The transition will bring a change in the administration’s senior leadership, with Miller moving from his current deputy position into one of the most influential roles in the White House.
