Now president obama and the first family making a historic visit to the infamous prison that held nelson mandela for 18 years. This was after the president and the first lady spent time on the phone with his wife who is by his side in the hospital where he is in critical condition. Jonathan karl is traveling with the president. Reporter: Good morning. For the obama family, today is the emotional high point of the president's trip to africa. They are making a pilgrimage out to robin island, the place where nelson mandela was a prisoner for 18 of his 27 years in prison. They will go out and visit the cell where he spent all of those years. Their guide is an 83-year-old former inmate at the prison. This is somebody president obama knows from 2006 when he visited as a senator, and toured with the same former prisoner. It's a tradition for the former inmates to give the tours. It was an awful prison camp, and before that a leper colony, and now it's a monument for the anti-apartheid cause. It's a tribute to nelson mandela, in ill health, critical condition on life support. At every stop along the way, president obama has had something to say about mandela, talking about him as a personal hero, someone who inspired him to get involved in politics in the first place, and indeed is a hero to the world.
