Donald Trump has blasted a union leader who accused him of lying about his deal to stop an air conditioning maker from moving jobs to Mexico.
The US president-elect said Chuck Jones had done a “terrible job” for workers at Carrier, moments after Mr Jones had criticised Mr Trump on CNN.
Mr Trump had wrongly claimed 1,100 jobs in Indiana were saved, said Mr Jones.
Earlier in the week Mr Trump attacked Boeing, hours after its boss criticised his trade policy, but he denied a link.
Shortly after Mr Trump’s tweet attacking Mr Jones on Wednesday night, the union leader started receiving phone calls threatening his children, he said.
“Nothing that says they’re gonna kill me, but, you know, you better keep your eye on your kids,” said Mr Jones.
Keeping jobs from migrating to lower-wage countries was a central plank of Mr Trump’s successful election campaign.
