Mr. Tillerson, a former chief executive of Exxon Mobil, has made no secret of his belief that the State Department is a bloated bureaucracy and that he regards much of the day-to-day diplomacy that lower-level officials conduct as unproductive. Even before Mr. Tillerson was confirmed, his staff fired six of the State Department’s top career diplomats, including Patrick Kennedy, who had been appointed to his position by President George W. Bush. Kristie Kenney, the department’s counselor and one of just five career ambassadors, was summarily fired a few weeks later.
