All 50 states, D.C., and four U.S. territories signed off on the multi-billion dollar settlement proposal with OxyContin maker Purdue Pharma in litigation over Purdue's alleged role in America's opioid addiction crisis.

Under the terms of the deal, Purdue Pharma will become a public benefit company, with profits directed toward opioid addiction.

State Attorney General Letitia James said Monday 55 states and territories have agreed to a settlement with Purdue over its major role in the opioid crisis.
