Dozens of scientists from universities and environmental groups are pushing for the removal of the head of the U.S. Fish and Wildlife Service, claiming she lacks the educational background required to run the agency despite securing Senate confirmation last year. The concerns over the credentials of service Director Martha Williams were outlined in a letter from 100 scientists sent Wednesday to President Joe Biden and U.S. Interior Secretary Deb Haaland. Williams is an attorney who majored in philosophy, and her critics claim she does not have the science-based education that federal law says is required for the position.
