The asnwer is in this excerpt from Media Natters in America's website. This is a story about a 2006 US Senate bill S2125, that informs ones about what US Senator Barack Obama, D Ill  would do more ( if elected president) in favor of the DR Congo. While the Congo was undergoing a contested electoral process that was preceded by a civil war, an estimated 3.9million people have died from war-related

causes since the conflict in the Democratic Republic of the Congo began.Nearly 80 percent of Congo's 56 million people live in extreme poverty and more than 70 percent are undernourished. The United Nations has its largest peacekeeping force in the world in the Congo, and in the summer of 2006, the country held competitive national elections for the first time in more than 40 years.
