WILMINGTON, Del. (AP) — Attorneys for Meta shareholders asked a Delaware judge Monday to sanction the company's former Chief Operating Officer Sheryl Sandberg and fellow Facebook board member and current White House chief of staff Jeff Zients for deleting emails related to the Cambridge Analytica privacy scandal, despite being told to preserve such records. The plaintiff attorneys contend that Sandberg and Zients used personal email accounts to communicate about key issues relating to their 2018 shareholder lawsuit that alleged Facebook officers and directors violated both the law and their fiduciary duties in failing for years to protect the privacy of user data.
