"My struggles have been around protecting our air quality, protecting people from mercury in fish. I was very involved in the effort to get the FDA to recognize that mercury in fish is a real health issue and the FDA, you know, needed to be on that. But they were very tight with the fishing industry and did not want the public to be aware in the same way that they later didn't want the public to be aware of the problems with Vioxx, and they sat on the studies for many years and allowed 140,000 people to develop heart disease."
