WASHINGTON: Susie Wiles will be the latest occupant of the hottest hot seat in Washington — Donald Trump’s chief of staff. It’s a tough job under the best of circumstances, responsible for networking with lawmakers, administration officials and outside groups while also keeping the White House running smoothly. But it’s been particularly challenging under Trump, who has a history of resenting anyone who tries to impose order on his chaotic management style. Four people served as chief of staff during his first term, and sometimes things ended on acrimonious terms.
