During an event in Iowa on Saturday, Republican presidential front-runner Donald Trump bragged that his supporters are so loyal that they would still vote for him even if he stood in the middle of New York City and shot someone.

"My people are so smart -- and you know what else they say about my people? The polls?" Trump asked a crowd at a rally at Christian liberal arts school Dordt College in Sioux Center, Iowa, reported ABC News. "I have the most loyal people -- did you ever see that?"

"I could stand in the middle of Fifth Avenue and shoot somebody, and I wouldn't lose any voters, OK?" Trump told the crowd as he put his fingers into the shape of a gun and acted like he was pulling a trigger, eliciting laughter. "It's like, incredible," Trump added.

Despite issuing numerous of controversial statements since entering the race, Trump continues to hold a huge lead nationally over the rest of the Republican field - 17 points ahead of his closest rival Sen. Ted Cruz of Texas in a recent CBS/New York Times poll. However, in Iowa, Cruz has recently caught up with Trump and even surpassed the bombastic real estate mogul in some polls.

Trump has joked about murdering people in the past, according to CNN. Referring to "horrible" and "scum" media, Trump said: "I hate some of these people, I hate 'em."

"I would never kill them. I would never do that," he said, going on to reconsider. "Uh, let's see, uh?"

"No, I would never do that," he concluded.

Also at the speech on Saturday, Trump pondered whether he should file a lawsuit against Cruz, challenging his eligibility for president. "I've said Ted has a lot of problems - number one, Canada. He could run for the Prime Minister of Canada and I wouldn't even complain because he was born in Canada," Trump joked, according to The Hill. "The Democrats are going to sue if he ever got the nomination within two days. There have already been two lawsuits filed, but they don't have standing. I have standing to sue. Can you imagine if I did it? Should I do it just for fun?"

But Trump said that he thinks he will beat Cruz without needing to file a suit. "If I thought it was going to matter, maybe I would do it, maybe I wouldn't," he said.
