 Everything you need to know about President Trump happened in the immediate aftermath of the shooting. The assassin nearly blew the man's head off, but he stood to his feet with blood streaming down his face, and he raised his fist in the air, a defiant Trump shouting, fight, fight, fight. That moment captured on camera by a New York Times photographer, a picture that will no doubt be published in the history books, a photograph that defines a moment in American history, a portrait of courage under fire.
