"I can give you one example where I would no longer support Donald Trump. If for example, he were to go out on Fifth Avenue and shoot somebody, I would not be willing to support Donald Trump," Cruz said today at a press conference in Rockford, Illinois.
Cruz’s reference is to when, back in January, Trump joked at a campaign rally in Sioux Center, Iowa, that his supporters would stand behind him even if he shot someone.
"I could stand in the middle of Fifth Avenue and shoot somebody, and I wouldn't lose any voters, okay?" Trump said, while putting his fingers into the shape of a gun and acting out pulling the trigger.
When pressed further by reporters, Cruz argued that he is a man who keeps his word.
"I know it is a shocking concept to members of the media. A shocking concept that an elected official actually does what he said. At the outset of this campaign, I committed I will support the Republican nominee. I honor my word," Cruz said.
"You’re not going to get me to answer a yes-or-no question," Kasich said Sunday. "I hope he’s going to change his rhetoric and bring people together."
