PHILADELPHIA (AP) — The attorney general of Pennsylvania says he’s filing a lawsuit accusing a pharmaceutical giant of fueling the opioid epidemic. Attorney General Josh Shapiro’s office said it would announce details of the lawsuit Tuesday afternoon. Pennsylvania is one of the states hardest hit by opioid addiction. Shapiro’s office two years ago joined with dozens of other states to investigate companies that make and distribute opioid painkillers. Several Pennsylvania counties have already sued drugmakers.
