 The sound of shots ringing out. Bodyguards immediately dived on Donald Trump and others raced onto the stage as well. The president himself got back onto his feet pretty quickly. People could see blood running from his right ear. But he raised his fist, he pumped the air before being bundled away in a waiting vehicle. One person was killed in that shooting. Two were injured. Among the supporters left behind, there was a mixture of confusion, anger and defiance.
