President Trump is about to make his debut at an institution he has often berated. For the first time, he will attend the annual United Nations General Assembly in New York, which brings together leaders of the 193 member nations for a week of meetings and speeches.
As president-elect, he called the U.N. "just a club for people to get together, talk and have a good time."
But it's a "new day" at the U.N., said U.S. Ambassador to the United Nations Nikki Haley.
