Stephen Miller will take over on November 9
Miller is one of Trump’s longest-serving political advisers.
He joined Trump’s first presidential campaign as a speechwriter in 2016 and later became a senior policy adviser in the first administration.
During Trump’s second administration, Miller has been closely associated with immigration, border enforcement and the development of the president’s broader policy agenda.
His promotion gives him responsibility for coordinating the White House staff, managing the flow of information to the president and helping organize the administration’s legislative and political strategy.
Trump described Miller as a trusted adviser in announcing the appointment.
The president also said Wiles would move to the Trump political operation rather than leave his broader political organization.
Susie Wiles will leave the chief of staff role
Wiles became Trump’s chief of staff at the start of his second administration after serving as one of his senior campaign managers.
She was widely viewed as a central figure in organizing the White House and managing access to the president.
Her departure from the chief of staff position comes days after Republicans suffered major losses in the November 2026 midterm elections.
The change represents a significant shift in the structure of Trump’s inner circle.
Wiles was associated with campaign organization and internal discipline, while Miller has been a more prominent public voice on immigration and executive policy.
What Miller’s appointment could mean
The chief of staff does not set policy independently, but the position can shape which issues reach the president, how decisions are carried out and how the White House deals with Congress and federal agencies.
Miller’s appointment may place a greater emphasis on the administration’s existing priorities, including immigration enforcement, border security and the implementation of Trump’s domestic agenda.
It also comes at a politically difficult moment for the administration.
With Democrats set to control Congress after the midterm elections, the White House is likely to face more resistance to legislation, oversight pressure and negotiations over government funding.
The White House will need to manage those challenges while maintaining coordination among senior advisers, cabinet departments and the president’s political operation.
Miller’s role in the Trump administration
Before becoming chief of staff, Miller served as deputy chief of staff for policy and homeland security adviser.
The White House has identified him in those roles in official materials and public events during Trump’s second term.
He has been an influential adviser on immigration policy and has helped shape the administration’s approach to enforcement, asylum and border operations.
Miller also played a prominent role in Trump’s public messaging during the president’s first term.
His move into the chief of staff position now places him at the centre of both policy coordination and White House operations.
What happens next
Miller is expected to begin as chief of staff on Monday, November 9.
The administration has not yet provided a detailed public description of Wiles’s responsibilities in the Trump political operation.
Further personnel changes could follow as the White House responds to the midterm results and prepares to work with a Congress controlled by the opposing party.
For now, the appointment makes Miller the main internal coordinator of Trump’s presidency and marks the first major White House leadership change since the midterm elections.
