In four payments from June to December 2014, Duke sent the Republican Governors Association a total of $3,050,000 A new analysis of government records reveals that Duke Energy – the world’s largest private electric utility – began writing unusually large checks to the national Republican Governors Association while Gov. Pat McCrory and Republican lawmakers debated how to respond to the company’s giant spill of coal ash sludge into the Dan River. In four payments from June to December 2014, Duke sent the Republican Governors Association a total of $3,050,000 – more than 10 times its previous record donation to the RGA.
