Big hearted Don

One man said he lived in Greenwich, Connecticut, where Mr Trump has a home, and there were plans to relocate Syrian refugee families there.

He asked Mr Trump if he could "look children aged five, eight, ten, in the face and tell them they can't go to school here".

Mr Trump did not hesitate and said he could, which brought applause from the crowd.

He said: "I can look in their faces and say 'You can't come'. I'll look them in the face.

"Look, we don't know where their parents come from. Their parents should always stay with them, that's very important, but we don't know where the parents come from, they have no documentation. They may be Isil, they may be Isil-related. It could be a Trojan horse. If two per cent of those people are bad the trouble is unbelievable."

Mr Trump added: "I have a bigger heart than anybody in this room. What we do is take an area, or areas, of Syria and build safe zones."

"I don't think they should be moving into Greenwich, Connecticut," he said. "I don't think they should be coming into the United States."

Trump also said he was suspicious of the refugees' cellphones:

You see them on cellphones. Where the hell did they get their cellphones? This is a migration. They have no anything, and yet they have cellphones. And then they have cellphones with ISIS flags on them …

Where the hell did they get the cellphones? Who the hell pays the bill? Who's paying the bill for the cellphone? And you see little things like that. Does that make any sense, OK? But you look at it and you say, "We have enough problems."
