Washington (CNN)Former President Barack Obama's tweet reacting to the attack in Charlottesville, Virginia, is the most liked tweet ever on the social network.
Obama tweeted a quote from Nelson Mandela's 1994 autobiography "Long Walk to Freedom" Saturday that said,

"No one is born hating another person because of the color of his skin or his background or his religion. People must learn to hate, and if they can learn to hate,
they can be taught to love, for love comes more naturally to the human heart than its opposite."
