The indictments came as Democrats on Capitol Hill grilled the CEOs of U.S. gunmakers Daniel Defense and Ruger Firearms over their role in U.S. mass shootings. House Oversight Chair Carolyn Maloney said an investigation by her committee found major gun manufacturers have raked in over $1 billion in revenue from selling military-style assault weapons to civilians.

Rep. Carolyn Maloney: “Our investigation also found that gun manufacturers use dangerous marketing tactics to sell assault weapons to the public. That includes marketing to children, preying on young men’s insecurities and even appealing to violent white supremacists. Finally, we found that even as guns kill more Americans than ever, none of those companies take even basic steps to monitor the deaths and injuries caused by their products.”
