New York Rep. Elise Stefanik, a strong ally of former President Donald Trump, has been nominated to serve as the U.S. Ambassador to the United Nations. Stefanik has been a leading voice against antisemitism on college campuses and has grilled college leaders over their handling of the issue. She has also supported Trump amid his criminal trial and has filed ethics complaints against the presiding judge. As U.N. ambassador, Stefanik is expected to bring a more attentive and engaged approach to the role, and the U.N. is bracing for a shake-up under the Trump administration.
