“When Mexico sends its people, they’re not sending their best,” he said on the day he announced his presidential campaign in 2015, saying some of those crossing the border were “rapists.”

“How do you stop these people? You can’t,” Trump said at a May 2019 rally in Panama City Beach, Fla. When someone in the crowd yelled back, “Shoot them,” Trump joked, “Only in the Panhandle can you get away with that statement.”

"How do you stop these people? You can’t,” Donald Trump said at a rally in Florida in May. The response from someone in the crowd came immediately: “Shoot them.” The audience laughed and cheered. Trump smirked and made a joke about it.

“Them” meant Latino immigrants and refugees that day.
