During her debate with Donald Trump, Hillary Clinton implored, “please, fact checkers, get to work.” Heeding her own call, her boast that while she was seretary of state exports to China increased 50 percent definitely needs to be put in context.

First, from a mathematic perspective, she was being a bit modest. Exports grew slightly more than 52 percent. In 2008, U.S. exports to China when Secretary Clinton assumed office were $71.5 billion. In 2012, at the end of her term, total U.S. exports to China were valued at $109 billion. But correlation is not causation.
