A Newsweek investigation has found that in two of Donald Trump's last three construction projects he used Chinese steel and aluminum instead of buying U.S. steel and aluminum from companies in Pennsylvania, Ohio, Michigan and Wisconsin.

Even as Trump uses Chinese steel and aluminum he's trying to sell workers on the idea that he's supposedly on their side when it comes to trade with China.

The Newsweek story says Trump's use of Chinese steel has deprived "untold millions of dollars from four key electoral swing states" and sent that money to China instead.
