United Nations Issues: Congressional Representatives to the U.N. General Assembly [August 1, 2018] [open pdf - 329KB]
"The annual session of the United Nations (U.N.) General Assembly is held at U.N. Headquarters in New York City. Generally, the President appoints one Democrat and one Republican to serve as U.S. representatives to the session, alternating each year between the House and Senate. At the 72nd session of the Assembly, which opened in September 2017, two House members (Barbara Lee and Christopher Smith) served as congressional representatives. Two members of the Senate will likely serve as representatives to the 73rd Assembly session, which is scheduled to open on September 18, 2018."
