Trump threatens to impose 25% tariff on Apple, Apple shares fall nearly 4% before the market opens

U.S. President Trump said on social media that he told Apple's Tim Cook a long time ago that I hope their iPhones sold in the United States will be manufactured and produced in the United States, not in India or anywhere else. If not, Apple must pay at least 25% tariff to the United States.

The market situation shows that Apple (AAPL.O) fell nearly 4% in pre-market trading.
