This week (Sept. 20), President Obama made his final appearance as US president at the United Nations General Assembly in New York. In his address, he urged the international community not to be divided along the lines of tribe, race, and religion. Obama also hosted one of two special summits on the global refugee crisis. In a joint statement after the summits, world leaders pledged to accept more refugees and commit more money to humanitarian aid. They also promised to expand refugees’ access to education and employment. Several faith-based groups played a key role in the effort.
