Overview

  • Katie Miller left the Trump administration in June to become a senior adviser in Elon Musk’s newly formed Department of Government Efficiency, leveraging her special government employee status.
  • Stephen Miller continues as White House deputy chief of staff, with top aides asserting that his position remains secure despite his wife’s shift to Musk’s team.
  • The public fallout escalated when Musk backed the potential impeachment of Trump in favor of Vice President JD Vance and Trump warned he might pull federal contracts from Musk’s companies.
  • Musk unfollowed Stephen Miller on X last Thursday, underscoring the personal dimensions of the high-profile dispute.
  • Senior White House officials are split over the dispute’s impact, with some cautioning that the Millers’ divided allegiances could complicate Stephen Miller’s political trajectory.
