Donald Trump has chosen Republican U.S. Representative Elise Stefanik to serve as U.S. ambassador to the United Nations. Stefanik, a Harvard-educated lawmaker from New York state and Republican Conference chair in the House of Representatives, has been a fierce Trump ally. Her nomination is subject to Senate approval, which is expected after her fellow Republicans regained control of the upper chamber in last week's elections. The United Nations has been planning for Trump's return and the cuts to U.S. funding and engagement with the world body that are likely to come with his second four-year term as president.
