After railing against his comedic portrayal on Saturday Night, Donald Trump on Sunday morning turned his Twitter account on corporate tax dodgers, announcing that while he intended to push for a lower overall corporate tax rate, "any business that leaves our country for another country, fires its employees, [or] builds a new factory or plant in the other country, and ... sell[s] its product back into the U.S." would face a sizable 35% tariff, reports the New York Times. That's equal to the current corporate tax rate, which Trump has said that he wants to lower to 15%, reports CNN Money, which notes that many economists are concerned that protectionist policies could harm the economy. Trump continued: "Please be forewarned prior to making a very expensive mistake! THE UNITED STATES IS OPEN FOR BUSINESS." (More Donald Trump stories.)
