WHAT WENT WRONG: In 2007, Christopher De Rosa noted formaldehyde contamination in Federal Emergency Management Agency trailers that house Hurricane Katrina evacuees, warning that the agency had not adequately addressed the long-term health effects of exposure. De Rosa also supervised a controversial report for the Centers for Disease Control and Prevention that discussed elevated infant mortality and cancer rates in the Great Lakes region. The CDC suppressed the report for almost a year, finally releasing a heavily edited version in March 2008 after De Rosa's was declared "below expectations."
THE HEAVY: Howard Frumkin, director of the National Center for Environmental Health.
THE PRICE: Frumkin removed De Rosa from his leadership position in 2007. Citing whistle-blower protection, the House Committee on Science and Technology has asked the CDC to offer an explanation.
