“Wrong and misleading” is how Office of Science and Technology Policy Director John Marburger described a recent Union of Concerned Scientists report criticizing the scientific integrity of the Bush administration. In a detailed 20‐page response to Congress and an accompanying summary released to the public on 2 April, the administration refuted point by point the UCS's claims (see http://www.ostp.gov). “I hope this response will correct errors, distortions, and misunderstandings in the Union of Concerned Scientists' document,” he said. “The bottom line is that we have a strong and healthy science enterprise in this country of which I am proud to be a part.”
