Facebook falls following report that Zuckerberg emails link him to controversial privacy practices.

Facebook stock dipped on a Wall Street Journal report that the corporate has uncovered emails linking chief executive officer Mark Zuckerberg to the social media giant’s controversial privacy practices.

Shares were down over 2% following the news. The report says employees at the corporate are concerned that the emails could come under scrutiny during an investigation from the Federal Trade Commission.

The FTC is investigating whether or not security lapses associated with the Cambridge Analytica scandal violated a 2012 consent decree between the agency and Facebook, according to the report.

The emails, which were described to the Journal reporters but not seen, reportedly show that Zuckerberg raised questions about how the corporate was sharing information with third-party developers, suggesting he knew of potential issues.

In an e-mailed statement, a Facebook spokesperson said, “We have absolutely cooperated with the FTC’s investigation to date and provided tens of thousands of documents, emails and files. We are continuing to work with them and hope to bring this matter to an appropriate resolution. Facebook and its executives, as well as Mark, at all times strive to comply with all applicable law, and at no point did Mark or any other Facebook employee knowingly violate the company’s obligations under the FTC consent order.”
