President-elect Donald Trump said he’s “making progress” in his effort to prevent Carrier from moving a factory abroad, an issue that had become a rallying cry during his campaign.

“Will know soon!” he said Thursday on Twitter, saying he was working even on Thanksgiving to keep the plant in Indiana.

Carrier replied with a tweet of its own, saying it had held discussions with Trump’s team and looked forward to working with the incoming administration. “Nothing to announce at this time,” said the company, which earlier this year said it would eliminate 1,400 jobs by relocating the plant’s manufacturing work to Mexico.

It was the second time in a week that the president-elect asserted that he had intervened to keep a manufacturing plant from leaving the country. Last week he said he helped persuade Ford Motor Co. to keep a plant in Kentucky, though the company said it never intended to close the facility.

The decision to move Carrier’s furnace factory garnered national notice after a worker’s cell-phone video of the announcement to employees took off on social media and generated criticism of Carrier parent United Technologies Corp. In April, Trump said he would impose a hefty tax on Carrier’s Mexican-made products and “within 24 hours, they’re going to call back: ‘Mr. President, we’ve decided to stay. We’re coming back to Indianapolis.”’

A representative of Farmington, Connecticut-based United Technologies declined to comment beyond Carrier’s tweet. Representatives of Trump’s transition team didn’t respond to a request for more information on the Carrier talks.
