Who is Susie Wiles, the 'ice maiden' who will be Donald Trump's chief of staff?

President-elect Donald Trump announced that Susie Wiles, one of his two campaign managers, will be his White House chief of staff, entrusting a top position to a political operative who helped the Republican win election. The appointment was the first of what is expected to be a flurry of staffing announcements as Trump girds for a return to the White House on January 20. As gatekeeper to the president, the chief of staff manages White House staff, organizes the president's time and schedule, and maintains contact with other govt depts and lawmakers. The low-key Wiles will be the first woman to serve as White House chief of staff.
