And now, I stand before you, Mr. President -- Commander-in-Chief of the army that freed me, and tens of thousands of others -- and I am filled with a profound and abiding gratitude to the American people. "Gratitude" is a word that I cherish. Gratitude is what defines the humanity of the human being. And I am grateful to you, Hillary, or Mrs. Clinton, for what you said, and for what you are doing for children in the world, for the homeless, for the victims of injustice, the victims of destiny and society. And I thank all of you for being here.
