With support from the United States, the country of South Sudan gained its independence from Sudan in 2011. But two years later, this new nation became embroiled in civil war. The conflict, which is cut along tribal lines, has led to a man-made famine, accusations of mass rape and ethnic cleansing, and a massive refugee crisis. The international community, including the U.S. during the Obama administration, has struggled to bring the conflict to an end. On Saturday, in an exclusive rarely seen side of the war, NewsHour Weekend Special Correspondent Simona Foltyn and journalist Jason Patinkin traveled for days on foot through the African bush to meet an American citizen who's a leader among rebels fighting to change South Sudan's government.
