Politics & Science - Investigating the State of Science Under the Bush Administration:
"In a June 2003 draft report, HHS scientists found that racial and ethnic disparities in health care are “national problems” that are “pervasive in our health care system” and carry a significant “personal and societal price” After review by political appointees, however, the final version contained none of these conclusions. Released December 23, 2003, the National Healthcare Disparities Report is a case study in the manipulation of science."
