From the Document: "Today I'm honored to join the thousands of leaders--that's what you are, leaders--from across the country for the 2019 Prescription Drug Abuse and Heroin Summit. Very important. Everyone here today is united by the same vital goal: to liberate our fellow Americans from the grip of drug addiction and to end the opioid crisis once and for all."
