I want to know the answer to the following question:
Who was the core staffer to the legislation that worked for the EPA and continued to work in the Office of Endangered Species?
All the background I'm provided with is that "The staff, under Dr. Train's leadership, incorporated dozens of new principles and ideas into the landmark legislation; crafting a document that completely changed the direction of environmental conservation in the United States.". Is that enough to answer the question?
Answer: no
