The United Steelworkers Union clapped back at Donald Trump after he attacked union boss Chuck Jones and railed over union dues as a reason for jobs being outsourced overseas.

Trump’s attack on Jones spawned the hashtag: #ImWithChuck, which is trending, as well as #ImWithChuckJones.

The United Steelworkers tweeted: “Dues have helped us file 45+ cases against bad trade; saving jobs in tire, paper, steel, etc. We walk the walk.”

They were responding to Trump’s tweet:  “If United Steelworkers 1999 was any good, they would have kept those jobs in Indiana. Spend more time working-less time talking. Reduce dues.”

Of course, Trump’s comments are not based on fact. He railed against Chuck Jones’ who accused him of lying “his ass off” about the terms of the deal to keep Carrier from outsourcing jobs to Mexico during an appearance on CNN’s Outfront with Erin Burnett. Jones isn’t backing down. On Thursday morning he said, “He [Trump] didn’t tell the truth. He inflated the numbers and I called him out on it.”

Jones called out Trump for his lies and Trump acted exactly how a narcissist would, with vengeance and more lies.

#ImWithChuck because unions are our first line of defense against spiteful ignorant Trumpanzees corporatizing the world.

I'm a proud Union member. Even in public service, unions are the voice of the workers for better pay, retirement & benefits. #ImWithChuck

A man who says there shouldn't be minimum wage, tried to bully a man standing up for American workers #ImWithChuck

#ImWithChuck because workers united cannot be divided. Workers can accomplish great things when we work tougher. Trump's division FAILED
