  • Facebook Whistleblowers

    Several anonymous Facebook whistleblowers have exposed a shocking pattern of criminal activity on the platform. Facebook is aware of these widespread issues but has not taken real or meaningful steps to stop them. Congress must ensure that the Securities and Exchange Commission (SEC) does its job. Permitting criminal activity on a company’s property will ultimately impact the value of the company stock, harming investors.
