On February 10, 2016, Carrier Air Conditioner, a division of United Technologies, announced that it was moving its manufacturing operations to Mexico. A cellphone video shot by an employee and posted on YouTube rapidly went viral, making this particular plant closing a national news story, after which Donald Trump made the company's decision to move to Mexico, "a centerpiece of his stump speeches attacking free trade."[1] The move played a role in the Donald Trump presidential campaign, 2016, as a symbol of his protectionist position on international trade, and a lesser role in the 2016 presidential campaign of Bernie Sanders.
Shortly after becoming President-elect, Trump and Vice-President elect Mike Pence announced a deal with Carrier to keep some of the manufacturing jobs in Indiana, while others would still move to Mexico, in exchange for large tax credits granted to the corporation.
