Veteran journalist Bill Moyers exposed decades of corruption of science and politics by companies, trade associations and PR firms defending the chemical industry in his March 26 documentary, Trade Secrets [3]. In the week leading up to the actual broadcast, the chemical industry launched its own attack [4] on Moyers, claiming that his documentary was unfair and biased. (For Moyers' response, click here [5].) In a speech at the National Press Club [6], Moyers gave additional details of the attacks that have attempted to dissuade PBS from airing the show. He also describes a previous and far more successful effort by chemical interests to suppress and falsely discredit a 1993 Moyers production about pesticides and children's health.
