President Donald Trump is threatening a 50% tax on all imports from the European Union as well as a 25% tariff on Apple products unless iPhones are made in America.

President Trump on Friday took aim at another giant corporation in his ongoing trade war, threatening Apple (AAPL) with increased duties if the company does not make iPhones in the US. He also attacked the European Union and said he was recommending a "straight 50%" tariff on EU-imported products beginning next weekend.
