Picture of the Day: Ban’s American Mom

U.N. Secretary-General Ban Ki-moon (L) visits the home of Libba Patterson, whom he refers to as his “American mom,” in San Francisco, California, on Aug. 11, 2016. Patterson hosted teenager Ban at her home when he traveled to the United States in 1962 on a student visit program. Ban, a former South Korean foreign minister, ends his 10 years as the U.N. chief at the end of this year. Standing behind them is Ban’s wife, Yoo Soon-taek. (Photo courtesy of the United Nations)
