A congressional panel will investigate why a federal agency is withholding a report describing potential health threats near 26 heavily polluted areas in the Great Lakes region, lawmakers said.

The handling of the matter by the Centers for Disease Control and Prevention “raises grave questions about the integrity of scientific research” at the agency, “as well as the treatment of its scientists,” U.S. Reps. John Dingell and Bart Stupak said in a letter Thursday to CDC Director Dr. Julie Louise Gerberding.

Dingell is chairman of the House Energy and Commerce Committee, while Stupak is chairman of its Oversight and Investigations Subcommittee. Both are Michigan Democrats.

CDC spokesman Glen Nowak said the agency would make an announcement soon about its plans for the report. Earlier this month, he said it was being revised to correct flaws.
