President-elect Donald Trump has appointed Stephen Miller as deputy chief of staff for policy. Miller, a long-time Trump adviser known for his hardline immigration stance, is expected to play a pivotal role in shaping the administration's immigration policies, including mass deportations. This position, not requiring Senate confirmation, continues Miller’s influence from Trump’s first term, where he was instrumental in controversial policies. His appointment signifies a strong focus on pro-American immigration reform amid varied pressures from business and GOP allies.
