The question about Zuckerberg's role leading the company he co-founded 13 years ago came a week after The New York Times reported that Zuckerberg and COO Sheryl Sandberg "ignored warning signs" of the Cambridge Analytica scandal that saw a political consultancy use data from millions of Facebook users. The company also knew about Russian influence activities on its platform as early as spring 2016, according to the report.

The Times reported that Facebook hired a firm called Definers Public Affairs to retaliate against or spread inflammatory information about its critics. On Friday, a group of Democratic senators sent a letter pressing the social network for more details about its relationship with Definers.
