United Nations Ambassador Nikki Haley resigned on Tuesday, and will leave her post at the end of the year. President Trump said Haley told him six months ago that she would want a "break" after two years in the administration, and praised her as "fantastic" in a joint press announcement. Haley shot down rumors of a presidential bid, saying she was "not running" in 2020. Her resignation was reportedly a shock to many top officials, including Secretary of State Mike Pompeo. A successor will be announced in the next "two or three weeks," said Trump, "maybe sooner." The former South Carolina governor said "nothing is set" in her future career.
