CAPE TOWN, South Africa (AP) — For years, the African National Congress rose above politics in South Africa. It was a movement dedicated to freeing Black people from the oppression of white minority rule and to the lofty principle of democracy, equality and a better life for all South Africans. It was widely revered as a force for good under Nelson Mandela, who spent 27 years in prison for his opposition to the apartheid system of racial segregation.
