Trump names immigration policy architect Stephen Miller as White House chief of staff

President Donald Trump has named Stephen Miller, his chief immigration policy architect, as the new White House Chief of Staff, replacing Susie Wiles. The announcement comes three days after Republicans suffered major losses in the midterm elections. Miller, a hardline adviser known for extreme anti-immigration positions, will assume the role on November 9, 2026. Wiles resigned Thursday night, becoming the first major casualty of the electoral defeat, amid controversy over her daughter's lobbying work for a Bosnian Serb entity. The appointment signals a shift toward even harder-line policies. Miller, 40, has been Trump's ideological guide for a decade and authored the mass deportation strategy. Democrats strongly oppose him, and his promotion may complicate cooperation with the new Democratic-controlled Congress.
