Trump replaces chief of staff Susie Wiles with Stephen Miller after midterm defeat

Following the Republican Party's devastating midterm defeat, US President Donald Trump is restructuring his inner circle at the White House. Chief of Staff Susie Wiles is stepping down, with Vice Chief of Staff Stephen Miller set to replace her starting Monday. Wiles, who also led Trump's presidential campaign, submitted her resignation Thursday evening, according to CBS News. The Republicans lost their majorities in both the Senate and the House of Representatives, a result Trump had framed as a referendum on his policies. Miller, 41, is known for hardline positions and was the intellectual root of Trump's policies, particularly on migration. Wiles, the first woman in the role, will remain in Trump's political orbit. She had announced in September she had overcome breast cancer.
