President-Elect Donald Trump doesn't spare anybody. Does he? On Wednesday (December 7), he took his usual route to slam on Twitter a person he didn't like.

Trump lashed out at Chuck Jones, president of United Steelworkers 1999 which represents employees of Carrier, saying he did a "terrible job representing workers" and added that "No wonder companies flee the country".

Jones had criticized the president-elect's claim that he has saved 1,100 jobs at a manufacturing plant in Indiana from being moved to Mexico, a country which Trump has been accusing throughout of stealing America's jobs.

Trump posted his attacking tweet soon after Jones expanded his remark made on Tuesday (Dec 6) that Trump "lied his a-off" -  on a CNN show. According to Jones, Trump's facts were not right when he announced that his deal with the air-conditioning company led to protection of several jobs.

"I think he ought to make sure he gets all the facts straight before he starts talking about what he's done," Jones told the show host Erin Burnett, according to a Politico report. Jones also responded to Trump's tweet, saying he was not worried with the president-elect blaming him and instead countered him asking how many millions of dollars he spent on his hotels and casinos to keep out the labor unions. Trump tweeted again later slamming United Steelworkers 1999 and suggested: "Spend more time working-less time talking".

Jones had voted for Hillary Clinton in this year's election and he called her "the better of the two evils", according to a Washington Post article.

National president of the United Steelworkers Union Leo Gerard also took Jones's side and expressed his disappointment with Trump. Speaking to MSNBC, Gerard said the would-be president of the US was busy tweeting about a local union president who he termed a "hero".
