President Trump speaks with U.S. Ambassador to the United Nations Nikki Haley before a meeting during the United Nations General Assembly at U.N. headquarters, Sept. 18, 2017. In early 2016, the then-South Carolina governor said she was “embarrassed” by candidate Donald Trump and decried his reluctance to condemn white supremacists. Nine months later, she agreed to join his Cabinet, serving as a key validator as Trump sought to win over skeptical world leaders and voters at home. (AP Photo/Seth Wenig, File)
