It’s not often that a top-level official in this Administration gets away clean and leaves on good terms with President Donald Trump. When she stepped down Tuesday as U.S. ambassador to the United Nations, Nikki Haley became one of the only senior staff members to walk away from the White House with her reputation largely intact. Since Trump’s first weeks in office, the White House has been plagued with high-profile departures of people who are fired or resign, often after being stung by scandal or caught up in some controversy: National Security Adviser Mike Flynn, FBI Director James Comey and Secretary of State Rex Tillerson, to name a few. But Haley, who is seen as stabilizing force within the Administration and a frequent spokesperson for the president’s foreign policy on television, left on her own terms with her political credentials preserved. In a decision that stunned Washington and the international diplomatic community, Haley announced she would leave her position by year’s end. The President’s send-off for Haley differed wildly from the typical announcements — often abruptly made from Trump’s personal Twitter account — that marked previous departures.
