>> reporter: good morning to you carol and alison. yes, even before president obama arrived whoer in south africa, he spoke of nelson mandela as being his personal hero. so the press conference that he held a short time ago with the current president jacob zuma, he summed up the feelings about the failing leader which lie it's in hospital behind me. it wasn't just his feelings that he summed up, but the feelings of so many people around the world. take a listen. >> our thoughts and those of americans and people all around the world are with nelson mandela and his family and all of south africa's. the struggle here, against apartheid, for freedom, madiba's moral courage, this country's historic transition to a free and democratic nation, has been a personal inspiration to me.
