"They’re keeping the rates artificially low so the economy doesn’t go down," Trump said in response to a question about a potential rate hike by the Federal Reserve this month. "So that Obama can say he did a good job. That's the only reason that the rates are so low. They're keeping the rates artificially low so that Obama can go out and play golf after January and say that he did a good job. But it is a very, a very false economy. So [Obama] can leave office and say: See I told you."

“We have a very false economy," he repeated.

"So far, I think she's done a political job," he said about Fed chair Janet Yellen.

"At some point the rates are going to have to change," Trump added. "The only thing that is strong is the artificial stock market."
