More to the point, his wealth has been accumulated through controversial coal-related businesses in his home state, including using his political muscle to keep open the dirtiest coal plant in West Virginia, which paid him nearly $5 million over the past decade in fees for coal handling, as well as costing West Virginia electricity consumers tens of millions of dollars in higher electricity rates (more about the details of this in a moment).
