Air conditioning company Carrier says it has reached a deal with President-elect Donald Trump to keep nearly 1,000 jobs in Indiana. Trump and Vice President-elect Mike Pence planned to travel to the state Thursday to unveil the agreement alongside company officials.

Trump spent much of his campaign pledging to keep companies like Carrier from moving jobs overseas. His focus on manufacturing jobs contributed to his unexpected appeal with working-class voters in states like Michigan, which has long voted for Democrats in presidential elections.

The details of the agreement are unclear. Carrier tweeted that the company was "pleased to have reached a deal" with Trump and Pence to keep the jobs in Indianapolis.

Trump said last week that he was "making progress" on trying to get Carrier to stay in Indiana.
