As the world remembers, we reflect on the life and legacy of South Africa's Nelson Mandela, Sunday on "This Week."

George Stephanopoulos speaks with four individuals who knew the former South African president - former U.S. Ambassador to South Africa Jendayi Frazer, former pollster for Nelson Mandela Stan Greenberg, Mandela biographer and former New York Times Johannesburg Bureau Chief Bill Keller, and Dr. Gay McDougall, former member of the Independent Electoral Commission of South Africa which oversaw the country's first fully democratic elections in 1994.

Plus, Sen. Dick Durbin, D-Ill., and Sen. Rob Portman, R-Ohio, debate the battle over the budget and income inequality, and our powerhouse roundtable weighs in on all the week's politics, with ABC News political analyst Matthew Dowd, author and Georgetown University professor Michael Eric Dyson, and political odd couple James Carville and Mary Matalin.

And in our "Sunday Spotlight," we look back at Nelson Mandela in his own words to ABC News in 1990 after his release from 27 years in prison.
