From Donald Kennedy's Editorial titled "Mixed Grill"

"Secrecy and concealment. I've complained about policy-makers in the U.S. administration who suppress scientific results if they don't support a particular political objective. Although most attention went to the case of Jim Hanson at the National Aeronautics and Space Administration and a few others, a rich lode of new material is opening up. Julie MacDonald, deputy assistant secretary for Fish, Wildlife, and Parks at the Department of the Interior, may be the champion science-buster of them all. The department's inspector general revealed that MacDonald interfered regularly by bullying staff to change recommendations on endangered species habitat, exposing the department to litigation. She resigned abruptly, shortly before being called to testify before Congress. And in a different space, the Federal Emergency Management Agency (FEMA) learned that some of the agency's trailers occupied by Hurricane Katrina victims had formaldehyde concentrations 75 times the maximum recommended dose. What did the general counsel do? He advised employees not to initiate testing because it might 'imply FEMA's ownership of the issue' and invite litigation. Representative Henry Waxman (D-CA), on learning this, pronounced it 'sickening…an official policy of premeditated ignorance.'"
