Donald Trump predicted terrorist attacks like the one that occurred in New York City on Saturday would continue to happen because the nation's leaders are "stupid."
"I knew this was going to happen," said the Republican presidential nominee during a Fox News interview on Monday while criticizingPresident Obama and Hillary Clinton's foreign policy positions.
"Thousands of people are pouring into our country, we have no idea what we are doing," he said. "Our leaders are, I don't even say weak, I say stupid."
The Republican presidential candidate said the problem is that too many people are being allowed into the country that "can't be properly vetted." He said the threat of terrorism is "only going to get worse ... you have to stop them from coming."
