Gun Owners of America executive director Sam Paredes called for California Attorney General Rob Bonta’s resignation over the incident.

He “is either massively incompetent, incredibly negligent, or willing to criminally leak information that he does not have the authority to leak,” Paredes said. “This is so egregious that he should resign. He has placed tens of thousands of abiding citizens in California in harm’s way. That is not excusable with an ‘I’m sorry.’”

In a statement on Wednesday, Bonta said, “I immediately launched an investigation into how this occurred at the California Department of Justice and will take strong corrective measures where necessary. The California Department of Justice is entrusted to protect Californians and their data. We acknowledge the stress this may cause those individuals whose information was exposed. I am deeply disturbed and angered,.
