Stephen Miller's rise to chief of staff signals a harder line after GOP losses

President Donald Trump replaced chief of staff Susie Wiles with longtime aide Stephen Miller after the GOP's midterm losses, signaling a more confrontational approach. The move came as Trump grew agitated over the election results and allies urged him to escalate his agenda. Miller, a hardline immigration advocate, was the architect of Trump's aggressive deportation campaign that sparked voter backlash and contributed to Republican losses. His appointment raised concerns among some Republicans, including Rep. Marlin Stutzman, who said the party misread voters' rejection of its governance. The shakeup is expected to derail potential immigration reform negotiations with Democrats, who now control Congress and have vowed to investigate the administration. Miller's elevation marks the culmination of his decade-long rise as one of Trump's most influential and controversial advisers.
