(CNN) -- Rep. Nick Lampson, D-Texas, said Tuesday that Federal Emergency Management Agency tried to control the outcome of a scientific study on formaldehyde in trailers used to house victims of Hurricane Katrina. FEMA trailers are shipped to the Gulf Coast by train in March 2006. "Someone from one of the agencies, the CDC, came to our committee and reported that he had information that indicated that good science wasn't followed when a decision was made to allow people to live in basically travel trailers that were not designed to be lived in," said Lampson, chairman of the Energy and Environment Subcommittee of the House Committee on Science and Technology.
