In March, Reg•Watch blogged about Julie MacDonald, one of the Bush administration's political minions who was manipulating environmental science to meet political ends. Yesterday, the Interior Department announced MacDonald's resignation. Interior is right to hold MacDonald accountable for her transgressions, but, as The New York Times reports, the move comes as the House Natural Resources Committee prepares to hold an oversight hearing next week on scientific integrity. Reg•Watch hopes MacDonald isn't just a sacrificial lamb. Union of Concerned Scientists Scientific Integrity Program Director Francesca Grifo welcomes the move, but also realizes MacDonald "represents a much larger problem of widespread political interference at federal agencies." The Bush administration should not always be on the defensive in reacting to violations of scientific integrity. Senior officials should take a proactive approach to weeding out those pushing political agendas in lieu of faithfully serving the public.
