Trump announced on Truth Social on November 6 that deputy chief of staff Stephen Miller will become White House chief of staff on Monday, November 9. Susie Wiles stays in the administration and moves to Trump's political operation. It is the biggest staffing change since Tuesday's midterms. Democrats now hold both chambers, and Miller's specialty is executive action that does not need Congress.
1
Miller's portfolio
Miller is deputy chief of staff for policy and homeland security adviser, and the main architect of second-term border and immigration policy. Fox News reports he also helped design executive-order plans on immigration, tariffs and spending.
2
Wiles shifts to politics
Wiles disclosed a breast cancer diagnosis in March 2026 and later said she showed no evidence of cancer. Trump publicly thanked her as she moves to the political team. Miller takes internal coordination; Wiles takes the political map toward 2028.
3
The executive-power math
The new Senate splits 54-44, leaving Democrats 13 seats short of the 67 needed to override a veto. Trump's veto stays decisive and executive orders remain the main policy tool. Miller's appointment is built for that structure.
Congress changed hands, so the White House changed gears. Miller's job is clear: push policy through executive action, protected by the veto.
