Rex Tillerson hasn’t even been confirmed as the State Department’s new secretary, but already the former Exxon CEO is already facing a mutiny from several top staffers. The State Department's entire senior level of management has resigned less than a week into Donald Trump's administration. The resignations, reported by the The Washington Post, included Patrick Kennedy, the agency's undersecretary for management who had served in the role for nine years. “It’s the single biggest simultaneous departure of institutional memory that anyone can remember, and that’s incredibly difficult to replicate,” David Wade, who served as State Department chief of staff under former secretary of state John Kerry, told the Post.
