One of Nelson Mandela’s grandsons said Friday he expects Mandela to be discharged from the hospital soon. And the man who succeeded Mandela as president, Thabo Mbeki, said in a radio interview that Mandela’s health is improving. Mandela, 94, has been in the hospital for two weeks, fighting a lung infection.However, what CBS News is hearing is completely at odds with statements from Mbeki. Sources tell us that Mandela’s liver and kidneys are functioning at 50 percent, and he had a procedure to repair a bleeding ulcer and another one to insert a tube.We’re told he hasn’t opened his eyes in days and is unresponsive. We also understand that Mandela family members are discussing just how much medical intervention is enough for an old and very sick man.
