Facebook Inc. faced criticism Wednesday from Republican and Democratic lawmakers who demanded that the social media company be more forthcoming about data it has shared with four Chinese firms.
The bipartisan criticism reflects rising frustration in Congress about how Facebook protects the privacy of the more than 2 billion people who use its services worldwide.
The leaders of the U.S. House of Representatives' Energy and Commerce Committee accused Facebook Chief Executive Officer Mark Zuckerberg of failing to disclose the company's agreements with the Chinese firms when he appeared before them in April and testified about Facebook's sharing of users' personal information with third parties.
