INDIANAPOLIS (AP) — Indiana political leaders are casting blame in different directions for a company’s decision to shut down a 1,400-worker factory in Indianapolis and move production to Mexico.

Democratic U.S. Sen. Joe Donnelly says he came away from a discussion with Carrier Corp. executives convinced the company is chasing lower labor costs in deciding to close the heating, ventilating and air conditioning factory over the next three years. The company announced its plans last week.

Republican Gov. Mike Pence cited federal regulations as contributing to the decision.

Donnelly says Carrier executives couldn’t specify any federal regulations to him. He says Carrier should return a $5.1 million taxpayer-funded federal tax credit it accepted in 2014.

Carrier spokeswoman Michelle Caldwell says the company hasn’t received and won’t claim the $5.1 million federal tax credit.
