Bipartisan Senators Demand Documents from Mark Zuckerberg After Newly Unsealed Court Filing Alleges Meta Hid Evidence of Harms to Kids from Congress & Public, Supporting Whistleblower Testimony

Newly unsealed disclosures suggest Meta executives’ direct knowledge of the harms of its products & concealment from Congress and the public, supporting whistleblower Arturo Béjar’s testimony to the Senate Judiciary Subcommittee on Privacy, Technology, and the Law

[WASHINGTON, D.C.] – A bipartisan group of Senators demanded Meta CEO Mark Zuckerberg provide documents related to senior executives’ knowledge of the mental and physical health harms associated with its platforms, including Facebook and Instagram. The Senators’ letter follows last week’s hearing with a new Facebook whistleblower and after a newly unsealed complaint filed by the Massachusetts Attorney General against Meta alleged Zuckerberg and other Meta executives knew firsthand the serious harms its products were causing to kids, but failed to act to remedy them and deliberately misled the public and Congress. 

“Meta’s representations to the public and in response to Congressional inquiries concealed and misrepresented its extensive knowledge about the threats to young people on its platforms,” wrote U.S. Senators Richard Blumenthal (D-CT), Chair of the Senate Judiciary Subcommittee on Privacy, Technology, and the Law, Marsha Blackburn (R-TN), Dick Durbin (D-IL), Chair of the Senate Judiciary Committee, Lindsey Graham (R-SC), Ranking Member of the Senate Judiciary Committee, Elizabeth Warren (D-MA), and Josh Hawley (R-MO), Ranking Member of the Senate Judiciary Subcommittee on Privacy, Technology, and the Law.

Last Tuesday, former Facebook executive Arturo Béjar testified before the Senate Judiciary Subcommittee on Privacy, Technology, and the Law about his efforts to inform Zuckerberg and other Meta executives about alarming internal research data on harmful experiences young people have on Instagram. “Rather than act on the stunning findings, Meta hid this information from the public and Congressional oversight while providing misleading statistics, ignoring recommendations to protect teens, and even rolling back safety tools,” continued the Senators.

Newly unredacted allegations in the lawsuit filed by the Massachusetts Attorney General corroborate Béjar’s testimony, suggesting the mental health risks of Facebook and Instagram were known widely within the company. “[E]xecutives are alleged to have repeatedly made decisions to implement changes to a product that they knew would harm teens and shelved safeguards based on concerns about their impact on revenue,” wrote the Senators, citing excerpts from the unsealed complaint in which Zuckerberg is alleged to have personally vetoed a new safety feature and the company’s continued underinvestment in platform safety staff. “It now seems clear that the root of Meta’s repeated failure to act to enhance the safety of its products starts at the top.”

The Senators called on Zuckerberg to provide to Congress directly a number of documents related to safety, including communications with Béjar and other communications between senior executives cited in the Massachusetts suit.

Mark Zuckerberg

Founder, Chairman, and Chief Executive Officer     

Meta Platforms, Inc.

1 Hacker Way

Menlo Park, CA  94025

Dear Mr. Zuckerberg:

            We write seeking documents regarding Meta’s research into, knowledge of, and response to the mental and physical health harms associated with its products, including Facebook and Instagram.

            Members of Congress have repeatedly asked Meta for information on its awareness of threats to young people on its platforms and the measures that it has taken, only to be stonewalled and provided non-responsive or misleading information. For example, in response to a question about teen mental health at a March 2021 House Committee on Energy and Commerce hearing, you testified that “overall, the research that we have seen is that using social apps to connect with other people can have positive mental health benefits and well-being benefits.”[1] In a response to a letter sent in August 2021, when asked a direct question about whether “Facebook’s research ever found that its platforms and products can have a negative effect on children’s and teens’ mental health or well-being,”[2] Facebook responded “we are not aware of a consensus among studies or experts about how much screen time is ‘too much.’”[3]

            Meta’s representations to the public and in response to Congressional inquiries concealed and misrepresented its extensive knowledge about the threats to young people on its platforms. Whistleblower documents provided to Congress in September 2021 directly contradicted your testimony, finding that a significant amount of teens on Facebook and Instagram “have an addicts’ narrative about their use,” “have only ‘a little control’ or ‘no control at all’ over how Instagram makes them feel,” and attribute to it suicidal ideation and body image concerns.[4] Despite these documented disclosures, Meta executives continued to downplay possible harms to young people in Senate hearings and inquiries.

            We are troubled by recent disclosures that shed further light on Meta’s knowledge of the harms its products cause teens and its unwillingness to take appropriate steps to prevent and mitigate these harms. Last Tuesday, former Facebook executive Arturo Béjar testified before the Senate Judiciary Subcommittee on Privacy, Technology, and the Law about his efforts to inform you and other senior executives at Meta of the dangerous and harmful experiences of teenagers on Instagram based on data collected by its internal researchers. As a result of Mr. Béjar’s efforts, Meta executives — including you, Sheryl Sandberg, Meta CTO Chris Cox, and Head of Instagram Adam Mosseri — knew that over half of Instagram users report having one bad or harmful experience each week, including a quarter of young teens reporting having received unwanted sexual advances. Rather than act on these stunning findings, Meta hid this information from the public and Congressional oversight while providing misleading statistics, ignoring recommendations to protect teens, and even rolling back safety tools.

            Mr. Béjar’s testimony and documents were corroborated by newly unsealed allegations in a lawsuit filed by the Massachusetts Attorney General. According to the complaint, the mental health risks of Facebook and Instagram were well-known within Meta. However, executives are alleged to have repeatedly made decisions to implement changes to a product that they knew would harm teens and shelved safeguards based on concerns about their impact on revenue. In one exchange, you are alleged to have personally vetoed a proposal to “disallow effects that mimic plastic surgery” that had significant support from Meta’s senior management and outside experts, despite a clear warning from Instagram’s Head of Policy that Meta would be “actively encouraging young girls into body dysmorphia.”[5] Additionally, while executives themselves acknowledged “wellbeing work is both understaffed and fragmented,” “currently underinvested,” and that Meta had been talking “about this for a long time but ha[d] made little progress,”[6] proposals to fund wellbeing work were denied, and safety staff has been subsequently cut from Meta. It now seems clear that the root of Meta’s repeated failure to act to enhance the safety of its products starts at the top. 

Given Meta’s apparent willful disregard for, and profiting from threats to, the safety and wellbeing of young people, as well as its misrepresentations to Congress, we write to request the following documents concerning your and other senior executives’ consideration of the requests for additional safety investments and tools detailed in Mr. Béjar’s testimony and in the complaint filed by the Massachusetts Attorney General. Please provide the following documents no later than November 30, 2023.
