Trump: Being in Terrorist Propaganda Shouldn't Stop Us From Speaking About the Enemy

On "The Factor" tonight, Bill O'Reilly asked Republican presidential front-runner Donald Trump about his first television ad, which appears to show illegal immigrants streaming across the U.S.-Mexico border.

"He’ll stop illegal immigration by building a wall on our southern border that Mexico will pay for," the narration says over the footage of people crossing the border, while the caption reads "STOP ILLEGAL IMMIGRATION."

Fact-checking website Politifact, however, found that the footage is actually of Moroccans trying to enter the Spanish enclave of Melilla in 2014.

Trump told O'Reilly that the ad wasn't purporting that this was the southern border, but instead showing what the border will look like if we don't make changes.

"We're like a third-world country. We're a dumping ground," Trump said. "It's really merely a display of what a dumping ground is going to look like. And that's what our country is becoming very rapidly."

You don't think the video is misleading? O'Reilly pressed.

"No, I think it's irrelevant," Trump said. "All we want to do is [show] what it's going to look like. They picked something, they could have picked something else. We could pick plenty of footage, that I can tell you, Bill."

O'Reilly argued that they should have used footage from the actual U.S.-Mexico border.

"You've got to be careful," O'Reilly pointed out. "You know that the media's after you."
