MADISON, Wis. (AP) — Wisconsin Attorney General Josh Kaul is refusing to join a multistate settlement with Oxycontin maker Purdue Pharma.

About half the states and thousands of local governments reached a tentative deal Wednesday with Purdue Pharma over its role in the nation’s deadly opioid epidemic. Sources with direct knowledge of the talks say Purdue Pharma will pay up to $12 billion and the Sackler family, which owns the company, will give up control.

But roughly half the states haven’t signed on to the deal, including Wisconsin. Kaul, a Democrat, said in a statement Wednesday that the Sackler family has made billions from opioid sales. He says the company’s settlement position doesn’t achieve justice.

Kaul spokeswoman Gillian Drummond says he will continue to pursue Wisconsin’s case.
