Whistleblower tells of America's hidden nightmare for its sick poor

Wendell Potter can remember exactly when he took the first steps on his journey to becoming a whistleblower and turning against one of the most powerful industries in America. It was July 2007 and Potter, a senior executive at giant US healthcare firm Cigna, was visiting relatives in the poverty-ridden mountain districts of northeast Tennessee. He saw an advert in a local paper for a touring free medical clinic at a fairground just across the state border in Wise County, Virginia. Potter, who had worked at Cigna for 15 years, decided to check it out. What he saw appalled him. Hundreds of desperate people, most without any medical insurance, descended on the clinic from out of the hills. People queued in long lines to have the most basic medical procedures carried out free of charge. Some had driven more than 200 miles from Georgia. Many were treated in the open air. Potter took pictures of patients lying on trolleys on rain-soaked pavements. For Potter it was a dreadful realisation that healthcare in America had failed millions of poor, sick people and that he, and the industry he worked for, did not care about the human cost of their relentless search for profits. "It was over-powering. It was just more than I could possibly have imagined could be happening in America," he told the Observer
