The agency that Margaret Hamburg has been running for the past six years likes to say that it oversees 20 cents of every dollar of consumer spending. She is leaving the post of commissioner of the Food and Drug Administration. We spoke on this program when she first came to Washington from New York City when she'd been commissioner of health. That was back in 2009. Doctor Hamburg, since we spoke at the beginning of your time at FDA, we thought we'd have an exit interview. Is that OK?
MARGARET HAMBURG: That's great. Yes - sort of bookends to the experience.
