Who is Stephen Miller, the Jewish Conservative promoted to Trump’s new chief of staff? - explainer

President Donald Trump promoted Stephen Miller to White House chief of staff after Republicans lost both chambers of Congress in the midterm elections. The appointment signals Trump's refusal to moderate policies, elevating the hardline immigration architect to one of Washington's most powerful positions.

President Donald Trump announced on Friday that Stephen Miller, 41, will replace Susie Wiles as White House chief of staff, following the Republican defeat in the midterm elections and the loss of both chambers of Congress. The appointment, which takes effect on Monday, signals a political choice: rather than moderate his policies after the electoral setback, Trump is promoting one of his most uncompromising architects. Miller, a Jewish conservative from a liberal Santa Monica background, rose from a controversial high school speaker to become a key architect of Trump's immigration policies, including travel bans, family separations, and reduced refugee admissions. He remained loyal after Trump's 2020 defeat, co-founding America First Legal, and returned as deputy chief of staff in 2025. His influence has extended into foreign policy, including discussions on Venezuela and Greenland. The article frames Miller as a figure who translates Trump's instincts into policy and now controls Oval Office access.
