Trump says China, others devalue currencies as U.S. economy improves

"We'll renegotiate our trade deals, stop the product dumping and the currency manipulation which is a disaster for our country," Trump said at a rally in Baton Rouge, Louisiana. "Every time we get going, China and others, they just knock the hell out of the value of their currency and we have to go back and back, and it just doesn't work, folks."
