WASHINGTON — Facebook Inc. is coming under fire from top U.S. lawmakers with the clout to regulate the social media powerhouse after the company revealed it had data-sharing partnerships with four Chinese consumer-device makers, including Huawei Technologies Co.

The leaders of the House and Senate commerce panels on Wednesday chastised Facebook Chief Executive Officer Mark Zuckerberg for keeping silent about the partnerships when asked at hearings in April about third parties that might be receiving users’ personal data from the company. Facebook also has missed a deadline to respond to follow-up questions from the Senate Commerce, Science and Transportation Committee, even after receiving an extension, Chairman John Thune said.

“All of this new information and new reporting I think raises even more questions,” Thune, a South Dakota Republican, said at the Capitol. “And they haven’t responded to the questions that we posed after the last hearings. So they have some explaining to do.”

‘WORKING ON ANSWERS’

Facebook said in a statement Wednesday that it plans to respond to questions from the Senate by the end of the week. “We are working right now to provide substantive answers to the over 2,000 questions we received coming out of the April hearings,” according to the statement.

The criticism adds to growing tension between Facebook and lawmakers from both parties, who are increasingly questioning the company’s data privacy and security practices.

Zuckerberg testified for 10 hours over two days in hearings triggered by revelations that a British firm with ties to President Trump’s 2016 campaign harvested information from as many as 87 million Facebook users without their knowledge.

The company on Wednesday confirmed the partnerships with four Chinese consumer-device makers after the New York Times reported about them. A top executive said that the company was careful with the information provided through the partnerships, which were designed to help smartphone makers build custom versions of Facebook’s app.

CONTROLLED INTEGRATIONS

“Facebook’s integrations with Huawei, Lenovo, OPPO and TCL were controlled from the get-go – and we approved the Facebook experiences these companies built,” Francisco Varela, the company’s vice president of mobile partnerships, said in a statement. “Given the interest from Congress, we wanted to make clear that all the information from these integrations with Huawei was stored on the device, not on Huawei’s servers.”

Facebook spokesman Andy Stone said the relationships didn’t need to be disclosed because they were already public, announced by Huawei at least twice in 2011. Facebook mentioned Huawei as one of its partners in a 2012 blog post. The company also said other technology companies had similar arrangements.

The disclosure adds to public distrust of Facebook, whose social network has more than 2 billion users worldwide, and which owns other popular divisions like Instagram, WhatsApp and Messenger.

Senator Mark Warner of Virginia, the top Democrat on the Senate Intelligence Committee, said on Tuesday that he saw a “a serious danger” that Facebook shared user information with Chinese device makers.

Thune and Sen. Bill Nelson of Florida, the Commerce panel’s top Democrat, asked Zuckerberg in a letter late Tuesday if he wants to now amend his April testimony that Facebook users have “complete control” over who sees their data and how it is shared.

In light of the new report about partnerships with Chinese companies, they also asked a series of new questions, including how data that is shared is stored and whether users or the Federal Trade Commission were ever aware of the data-sharing agreement. The company was given a June 18 deadline to respond.

‘HARD TO KNOW WHAT’S TRUE’

Nelson slammed Zuckerberg on the Senate floor Wednesday for failing to mention what the senator called “yet another example of questionable business practices by Facebook that could undermine basic consumer privacy.” He added, “It’s hard to know what’s true anymore.”

The concerns are being echoed in the House.

“At our hearing with CEO Mark Zuckerberg, bipartisan members of the committee asked direct questions about Facebook sharing personal data with third parties,” Energy and Commerce Committee Chairman Greg Walden of Oregon said in a joint statement Wednesday with the panel’s top Democrat, Frank Pallone of New Jersey.

“Clearly, the company’s partnerships with Chinese technology companies and others should have been disclosed before Congress and the American people,” they said.

“The spirit of our questions about third-party access to user data should not have required technical knowledge of the legal agreements Facebook has with device manufacturers to get clear answers for the public.”

Huawei said in an emailed statement Wednesday that it never collected or stored Facebook user data but had worked in the past with the social media company to make services “more convenient for users.”

Huawei, China’s largest maker of telecommunications equipment, was founded in 1988 by former Chinese army officer Ren Zhengfei. Congress has barred the Pentagon from buying Huawei’s gear, along with ZTE Corp., citing the companies’ connections to the Chinese government and the potential for intellectual-property theft and spying.
