LLAMAS: It comes amid a new battle over another high profile trip, Trump's visit to the Carrier plant. And his announcement he'd convinced the company not to send Indiana factory jobs to Mexico.

DONALD TRUMP: And now they're keeping, actually, the number is over 1,100 people, which is so great.

LLAMAS: Turns out, it's really 800 jobs, slated for Mexico, that were saved, not 1,100. 600Carrier jobs at that factory are still going across the border. Chuck Jones, the union leader representing those workers says Trump, quote, lied his expletive off.

CHUCK JONES: If you are dealing with people's livelihoods, you sure as the world ought to know what the numbers are.

LLAMAS: Less than 20 minutes later, the president-elect firing off these tweets; “Chuck Jones has done a terrible job representing workers. No wonder companies flee!” “Spend more time working, less time talking. Reduce dues.”

CHUCK JOHNS: He overreacted, President-elect Trump did.

[END CLIP]

LLAMAS: Jones says he's now getting death threats. It's the second time this week Trump has used Twitter to lash out at a critic. One hour after the CEO of Boeing was quoted questioning the president-elect's approach to China. Trump tweeting ; “Boeing is building a brand new 747 Air Force One for future presidents, but costs are out of control. Cancel order!”
