Stock futures across all three market indexes fell Friday after President Donald Trump threatened 50% tariffs on the European Union and at least 25% levies on Apple, whose stock was at the forefront of a broader market selloff, unless the company shifts iPhone production to the U.S.

President Donald Trump said iPhones made outside the US would incur a tariff of at least 25% and threatened to increase levies on European imports.

President Donald Trump said Apple must pay a 25% tariff if it doesn’t rely on domestic production of iPhones for the U.S. market.
