Billionaire Governor Jim Justice was elected governor of West Virginia as a Democrat but after election, he switched parties with Trump by his side.

Raw Story reports that Governor Justice, up for re-election, has stiffed hundreds of former workers in his coal mines.

Raymond Dye had a buildup of blood behind his left eye that prevented him from seeing. David Polk had an abnormal heartbeat, and his wife had high cholesterol. Roger Wriston’s wife had a bad back.

All the men had worked for a collection of coal companies owned by Gov. Jim Justice and his family, which had pledged to provide health insurance after the miners retired. Last year, though, the retirees learned that those firms had stopped paying their premiums. And as a result, their coverage had been terminated. Polk skipped doctor appointments.

“I know that waiting on medical treatment can do irreparable harm to my health,” he later said in a legal filing, “but I cannot afford to pay the bills.”

The expenses for the aging retirees, compounded by decades of work in southern West Virginia’s coal mines, were often costly. At one point, Wriston and his wife ended up with a bill for $12,367.76, another court filing said.

“I don’t think it’s fair what they’re doing to someone who worked their whole life,” Wriston’s wife, Tammy, said in an interview.

About 150 retired miners around West Virginia were making a similar discovery. So the United Mine Workers of America, the same miners’ union that had endorsed Justice’s election as governor in 2016, went to court last year and asked a federal judge to force the Justice companies to pay.

Lawyers for Justice’s companies initially opposed the union’s request for such an order, arguing the miners had not followed proper procedures for appealing a denial of health-benefit claims. Then, the companies settled, promising to clear up the matter and ensure benefits were provided.
