President Donald Trump launched a pair of fresh tariff threats via social media Friday, signaling a new 50% trade levy on import goods from the European Union could be assessed in a matter of days and a tariff of “at least 25%” on Apple iPhones manufactured outside the U.S. may also be in the works.

U.S. President Donald Trump said on Friday that a 25% tariff he says he will impose on Apple will also apply to Samsung and other smartphone makers. Trump, talking to reporters in the Oval Office, also said he was fine with leaving a 50% tariff in place on the European Union absent a trade deal.
