"The triumph of Nelson Mandela and this nation speaks to something very deep in the human spirit, the yearning for justice and dignity that transcends boundaries of race and class and faith and country," said Mr. Obama. "That's what Nelson Mandela represents. That's what South Africa, at its best, can represent to the world."
Mr. Obama along this trip - starting in Senegal, now in South Africa, later in Tanzania - is trying to increase U.S. development throughout Africa. There's been some criticism because this is the president's first extensive trip to sub-Saharan Africa of his presidency, the United States allegedly late to the game in development opportunities in Africa.
