President-elect Donald Trump's latest Twitter target is a local union official who questioned the billionaire's account of how many jobs he saved at a Carrier plant in Indianapolis.
Trump has previously used social media to browbeat companies that move jobs offshore as well as entertainers whose acts he finds tiresome.
On Wednesday, Trump took aim at Chuck Jones, president of the United Steelworkers Local 1999.
Trump wrote on Twitter that Jones "has done a terrible job representing workers. No wonder companies flee country!"
