Stephen Miller's Rise to White House Chief of Staff

President Donald Trump announced Friday that Stephen Miller will become his next White House chief of staff, replacing Susie Wiles after Republicans suffered major losses in the midterm elections. Miller, previously deputy chief of staff for policy, has orchestrated Trump's most polarizing policies, including a harsh immigration crackdown. Trump blamed Wiles for the worst Republican midterm performance in decades, and she resigned Thursday, according to sources. Trump considered special envoy Steve Witkoff and intelligence director Jay Clayton before settling on Miller, citing his loyalty and zeal in defending the president amid looming congressional investigations. Miller has been with Trump since his first campaign and expressed interest in the job for weeks. White House aides anticipate further personnel changes, with Wiles' deputies potentially vulnerable, while defense secretary Pete Hegseth may benefit from the shift due to his ideological alignment with Miller.
