Trump: 'Who The Hell Cares About a Trade War?'

Presumptive Republican nominee Donald Trump escalated his rhetoric against China's currency manipulation and the outsourcing of U.S. labor, defending his aggressive trade policies from conservative critics.

At his first rally in nearly two weeks, Trump struck a defiant tone as he promised to bring back American jobs. "We're losing $500 billion to China," he said at a fundraiser for endorser New Jersey Gov. Chris Christie.
