In February 2008, John D. Dingell (D-MI) and Bart Stupak (D-MI) of the United States House of Representatives announced that their ongoing investigation into Bisphenol A (BPA) had broadened to include The Weinberg Group. In March 2008, ABC News reported that the U.S. Congress was investigating the Weinberg Group. Representative John Dingell said, "The tactics apparently employed by the Weinberg Group raise serious questions about whether science is for sale at these consulting groups, and the effect this faulty science might have on the public health." The House Energy and Commerce Committee, which Dingell chairs, asked the firm for records of its work on Bisphenol A and other chemicals. Some studies indicate that Bisphenol A, which is present in a wide range of plastics, is an endocrine disruptor and "can disrupt hormone systems in laboratory animals and possibly increase the risk of cancer or other serious illness." Canada and ten US states have moved to ban the chemical from baby bottles, and in February the U.S. National Toxicology Program released a report concluding that "there is some concern for neural and behavioral effects in fetuses, infants, and children at current human exposures," and that "bisphenol A exposure in these populations based on effects in the prostate gland, mammary gland, and an earlier age for puberty in females."
