While 15 states including New York, New Jersey and Pennsylvania have agreed to a proposed settlement with Purdue Pharma and the Sackler family, Connecticut Attorney General William Tong says not so fast.

Tong, who has been one of the drugmaker’s fiercest critics over the past several years, said in a statement that the Nutmeg State—home base of Purdue Pharma, maker of OxyContin—wasn’t satisfied with the tentative agreement, which calls for Purdue and its owners to pay $4.5 billion for prevention and opioid addiction recovery programs, and that a New York bankruptcy judge must still sign.
