Haley, a former governor of South Carolina, was appointed as ambassador in 2016 shortly after Trump’s election. She was an outspoken critic of Trump prior to his election, so when he named her the envoy to the world body the appointment was seen as a peacekeeping move.

However, it appears any previously existing tension between them has been resolved, as the two continually emphasized their admiration for each other in an oval office press conference this morning. Trump said he believes Haley has helped make the position of UN ambassador “more glamorous” and “more important,” and said that “many people” want the job. He went on to say that, “She’s done a fantastic job, and we’ve done a fantastic job together,” adding that Haley has been, “very special to me.” Trump says he will announce the name of the new ambassador in two to three weeks.

Trump claimed that Haley informed him of her plan to resign several months ago, but The Hill reports that Haley’s staff and Secretary of State, Mike Pompeo, were supposedly “blindsided” by the news. President Trump said regarding Pompeo, “I can speak for Secretary of State Mike Pompeo. He thinks the world of Nikki.” Pompeo has yet to comment on Haley’s resignation.

Despite the abrupt nature of her departure, Haley was considered by many to have been a stabilizing force within the Trump administration. The New York Times describes her as, “someone whom foreign diplomats looked to for guidance from an administration known for haphazard and inconsistent policy positions.”

Peter Yeo, a U.N. Foundation official, told the Washington Post that Haley, “was critical in ushering in U.N. reforms in partnership with the secretary general, and she took a thoughtful approach to peacekeeping and national security issues.” He went on to say, “There certainly were great areas of contention between the United States and the U.N. But she played a very important and constructive role.”

Haley was the first cabinet United Nations ambassador for a Republican administration since the end of the Cold War. There has been some past speculation that Haley saw the position as a way to climb to a higher political post, which Trump may have resented. But Haley put any rumors of a 2020 presidential run to rest this morning, saying, “For all of you that are going to ask about 2020, no, I’m not running for 2020,” Haley said. “I can promise you what I’ll be doing is campaigning for this one. So I look forward to supporting the president in the next election.”

Haley described her job as US ambassador to the United Nations as the “honor of a lifetime.”
