Stephen Miller replaces Susie Wiles as White House chief of staff

President Donald Trump announced Friday that Stephen Miller will replace Susie Wiles as White House chief of staff, days after Republicans lost control of Congress in the midterm elections. Miller, a key architect of Trump's hard-line immigration policies, signals a resistance to conciliatory approaches. Miller, currently deputy chief of staff for policy, is one of Trump's longest-serving advisers, joining the 2016 campaign as a speechwriter. His promotion suggests a potential burst of executive actions in Trump's final two years, as he faces a Democrat-controlled Congress. Wiles resigned Thursday night and will continue with Trump's political organization. Wiles, the first woman to hold the post, was credited with bringing discipline to Trump's campaigns and served as his longest-tenured chief of staff. She recently revealed she was cancer-free after treatment. Miller's immigration policies were a liability for Republicans, with most voters disapproving of enforcement actions.
