Susie Wiles, the first female White House chief of staff, resigned after a disastrous midterm cycle that exposed her misguided confidence in Trump's electoral strength.
Trump accepted her resignation on November 13, 2026, signaling a rapid end to her two-year tenure amid mounting criticism over her failed predictions and the GOP's poor midterm performance.
Miller, a hard-line ideologue, now assumes the role, offering a stark contrast to Wiles's more pragmatic approach. His advocacy for aggressive border policies, expansive deportations, and aggressive military actions underscores a sharply different governing style. The transition highlights a deepening divide within Trump's inner circle, with critics warning that Miller's uncompromising stance could further polarize the administration and complicate efforts to rebuild public trust.
