(Portland, OR) -- Oregon is set to play a role in Apple's plans to invest 600 billion dollars in American manufacturing under President Trump. Apple CEO Tim Cook announced the investment alongside Trump at the White House on Wednesday. Cook says the investment, which is 100 billion more than what was originally pledged by Apple, will happen over the next four years. Apple says construction of an expanded data center is underway in Oregon, as well as in Iowa and Nevada. This comes as Trump pressures Apple to move its supply chain to the U.S. Trump is threatening 100 percent tariffs on imported semiconductors, which would impact Apple products like iPhones, iPads and MacBooks.
