U.S. Ambassador to the United Nations Nikki Haley said Tuesday she will step down from her post at the end of the year. Haley made the surprise announcement at the White House Tuesday alongside President Trump.

Nikki Haley: “Look at what has happened in two years with the United States on foreign policy. Now the United States is respected. Countries may not like what we do, but they respect what we do. They know that if we say we’re going to do something, we follow it through.”

Haley’s resignation reportedly caught Secretary of State Mike Pompeo and other top officials by surprise. During Haley’s time as U.S. ambassador to the U.N., the United States withdrew from the Paris climate accord; the U.N. Human Rights Council; the Iran nuclear deal; UNRWA, the U.N. agency that provides humanitarian aid to Palestinians; and UNESCO, the U.N. educational and cultural agency. Haley’s resignation came just a day after a government ethics watchdog called on the State Department to probe her use of several free flights on private jets, paid for by three different South Carolina businessmen.
