Trump names Stephen Miller chief of staff after midterm losses

President-elect Donald Trump has named Stephen Miller, the architect of his hard-line immigration policies, as his new chief of staff, replacing Susie Wiles, who will move to a political operation role. The change takes effect Monday. Miller, a loyal ally and senior adviser during Trump's first administration, will assume the position following Republicans' major defeats in the 2026 midterm elections, which saw the party lose control of both chambers of Congress. Trump praised Wiles' performance on Truth Social. Wiles, 69, considered one of the most powerful figures in the administration, called her service "the honor of a lifetime" while affirming her continued commitment to Trump's mission. Her departure follows a week of high-profile exits amid a Republican reckoning over voters' rebuke of Trump's agenda.
