A new report condemns the F-B-I for bungling another case — the investigation of a government scientist accused of leaking nuclear secrets to the Chinese.

Senator Charles Grassley says the F-B-I should have looked for other suspects.Grassley says the F-B-I has forgotten the fundamentals of law enforcement.Grassley says others who are guilty of spying for the Chinese may now go free because the trail’s cold.Grassley has been among those calling for management changes at the F-B-I. Lee, who was born in Taiwan, worked at the Los Alamos National Laboratory in New Mexico.
