I know something about lead poisoning because of the work I've done in the past (with Children's Defense Fund) and as a senator from New York, we had a lot of old housing with lead paint in it. A lot of kids suffered from lead poisoning, and part of the challenge is you've got to intervene early. We need comprehensive health screenings, then we need to figure out how do we get the right nutrition and vitamins. You've got to begin to work to counteract the lead.
