MS NOW reports that President Donald Trump announced Stephen Miller, an immigration hard-liner who helped execute his mass deportation agenda, will replace Susie Wiles as White House chief of staff on November 9, 2026, three days after midterm elections that rebuked his second-term policies. Trump thanked Wiles, who had resigned the night before, for her service as chief of staff, while some administration officials feared Miller's promotion would revive more extreme ideas and prominent Democrats vowed to investigate the immigration agenda.
