Pennsylvania Attorney General Josh Shapiro, along with 41 other state attorneys general, sent a letter to Facebook CEO Mark Zuckerberg demanding answers about the company’s business practices and privacy protections.

“Businesses like Facebook must comply with the law when it comes to how they use their customers’ personal data,” Shapiro said in a statement. “State attorneys general have an important role to play in holding them accountable and I’m proud to partner with so many of my colleagues from both sides of the aisle in this effort.”
