Harley-Davidson says it's shifting work overseas as a result of the trade fight going on between the US and Europe, and President Trump isn't taking the news lightly. In several tweets through Tuesday morning, the president criticized—and warned—the company. "A Harley-Davidson should never be built in another country-never!" Trump wrote. "Their employees and customers are already very angry at them. If they move, watch, it will be the beginning of the end - they surrendered, they quit!" Trump also accused Harley of using the tariffs being imposed by the EU "as an excuse" to justify the decision to ramp up production outside the US. "Harley must know that they won't be able to sell back into U.S. without paying a big tax!" he added. Related coverage and background:
