A former Meta executive, Sarah Wynn-Williams, testified before U.S. senators on Wednesday, alleging that the company compromised national security to build a lucrative business in China.

Wynn-Williams, who previously served as Meta's global public policy director, claimed that company executives allowed the Chinese Communist Party to access Meta user data, including that of American citizens, as part of efforts to expand its operations in China.

Meta, however, strongly disputed Wynn-Williams's accusations. "Sarah Wynn-Williams' testimony is divorced from reality and riddled with false claims," said Meta spokesperson Ryan Daniels. He added that while CEO Mark Zuckerberg has publicly expressed interest in operating in China, Meta does not currently offer its services there. Nevertheless, Meta does generate significant advertising revenue from Chinese advertisers.

During her testimony before the Senate judiciary subcommittee, Wynn-Williams also accused Meta of working closely with Beijing to develop censorship tools. She specifically cited the company’s decision to delete the Facebook account of Chinese dissident Guo Wengui, who lives in the U.S., after pressure from Chinese authorities. Meta maintains that Wengui's account was unpublished and suspended for violating its Community Standards.

Wynn-Williams described her personal experiences with the company's collaboration with the Chinese government, stating, "One thing the Chinese Communist Party and Mark Zuckerberg share is that they want to silence their critics."

In addition to her testimony, Wynn-Williams released a memoir, "Careless People," in March, which includes critical claims about her time at Facebook. Meta had sought to block the promotion of the book, calling it "false and defamatory."

Senator Josh Hawley, who led Wednesday’s hearing, accused Meta of trying to prevent Wynn-Williams from speaking out. He claimed the company had threatened her with financial penalties, alleging Meta intended to impose $50,000 in punitive damages each time she publicly mentioned Facebook.

Wynn-Williams shared that the ordeal had taken a personal toll on her, describing the decision to testify as incredibly difficult. "The last four weeks have been very difficult," she told the committee.

Meta's spokesperson did not directly address whether the company would pursue financial penalties in response to Wynn-Williams's testimony, but clarified that she was not prohibited from testifying before Congress. The ongoing legal disputes and accusations reflect growing tensions over the company's practices, both domestically and internationally.
