President Obama shook hands with Cuban president Raul Castro on his way down to the stage.
The crowd went absolutely wild as President Obama took the stage.

President Obama: "He was not a bust made of marble; he was a man of flesh and blood ... That is why we learned so much from him; that is why we can learn from him still."
"I have fought against white domination and I have fought against black domination. I've cherished the ideal of a democratic and free society in which all persons live together in harmony and with equal opportunities. It is an ideal which I hope to live for and to achieve. But if needs be, it is an ideal for which I am prepared to die."
Obama: "He changed laws, but he also changed hearts."
Obama: "Too many people embrace Madiba's reconciliation but reject any reforms."
Obama: "South Africa proves we can change... You, too, can make his life's work your own."
