Maine Attorney General Aaron Frey is among 47 attorneys general joining in a $573 million settlement with a consulting firm they claim profited off the opioid epidemic.

Attorney General Aaron Frey’s office said Thursday they were joining in the settlement with McKinsey and Company. He says the settlement resolves investigations into the firm’s role in working for opioid companies like Purdue Pharma and helping them “turbocharge” the sale of drugs such as OxyContin.

The settlement also calls for McKinsey to publicly disclose internal documents detailing it’s work for Purdue.

“This settlement is one step toward achieving accountability and redress for the harms caused by companies which aggressively pushed opioids into states like Maine and profited greatly from it,” said Frey. “McKinsey played a critical role in advising manufacturers like Purdue in how to market their product, so this settlement is appropriate. We will continue to aggressively pursue Purdue, the Sackler family, and other manufacturers and distributors responsible for this epidemic which continues to wreak havoc on our state.”
