Air conditioner maker Carrier said Tuesday it reached an agreement with President-elect Donald Trump to keep about 1,000 manufacturing jobs in the midwestern state of Indiana and not move them to Mexico. The company said on Twitter it is "pleased to have reached a deal," and that details would come "soon." Trump himself said he will go to Indiana to make a major announcement about Carrier. "Great deal for workers!" he boasted. A Trump transition team official said Vice President-elect Mike Pence, who is also the governor of Indiana, will join Trump to talk more about the agreement with Carrier officials on Thursday. One of Trump's frequent promises during his campaign for president was that he would prevent companies from moving jobs outside the country and bring back those that have already left by imposing stiff tariffs on products the companies wanted to sell in the U.S. It is unclear whether Carrier's parent company, United Technologies, will go through with plans to move jobs from a separate plant to Mexico.
