An opponent of Attorney General Patrick Lynch calls funds from the DuPont Co. lead paint settlement that were used to pay off a $1.5 million pledge by a private law firm to a Boston hospital, "the most amazing scam." William Harsch, a Republican who's running against Lynch in November, said Motley Rice, which worked on the DuPont settlement, used part of that money to pay off a pledge it had made to Brigham and Women's Hospital's asbestos program. Lynch pledged that some of the settlement money would go the hospital, supposedly for a lead paint prevention program. .
