WASHINGTON -- Facebook CEO Mark Zuckerberg acknowledged Wednesday that regulation of social media is "inevitable" and disclosed that his own personal information has been compromised by malicious outsiders. But after two days of congressional testimony, what seemed clear was how little Congress seems to know about Facebook, much less what to do about it.
Statements from representatives facing re-election this year ranged from complaints of anti-conservative bias to questions about whether Facebook could improve broadband speeds in their state.
Facebook shares rose more than 1 percent after climbing 4.5 percent on Monday. Rather than putting a dent in his well-prepared armor, two days of unfocused questioning helped Zuckerberg restore more than $25 billion in market value that the company has lost since thebroke in mid-March.
Facebook's stock remains 10 percent below where it stood before the scandal, a decline that has wiped out about $50 billion in shareholder wealth.
Wrapping up his four-minutes of questioning, Rep. Gus Bilirakis of Florida commended the platform, saying "it's wonderful for us seniors to connect with our relatives."
Other lawmakers were similarly stymied by the rapid-fire format, unable to probe beyond surface-level accusations that Facebook had breached users' trust.
Anna Eshoo, a California congresswoman whose district is adjacent to Facebook's Menlo Park headquarters, pressed Zuckerberg Wednesday on whether the company would be willing to change its business model to protect individual privacy. Zuckerberg said he wasn't sure what that meant, and Eshoo was forced to say she would follow up with written questions.
The House, however, was a tougher audience for Zuckerberg than the Senate, said CBSN anchor Tanya Rivero.
"They pushed Mr. Zuckerberg, and they pushed him on issues that didn't necessarily have to do with data gathering, data monitoring, but on a plethora of issues," said Dan Patterson, senior writer for TechRepublic.
Jennifer Grygiel, assistant professor at Syracuse University's Newhouse School of Public Communications, said she agrees with analysis that representatives in the House seemed to have a better grasp on how social media and the internet in general works, compared to senators who questioned him Tuesday.
"And they also had the benefit of listening to the testimony yesterday," she said.
At the close of Wednesday's hearing, Zuckerberg had spent roughly 10 out of the previous 24 hours testifying before Congress. On Tuesday, Zuckerberg batted away often-aggressive questioning from senators who accused him of failing to protect the personal information of millions of Americans from Russians intent on upsetting the U.S. election.
Lawmakers in both parties have floated possible regulation of Facebook and other tech companies amid privacy scandals and Russian intervention on the platform. It's not clear what that regulation would look like and Zuckerberg didn't offer any specifics.
"The internet is growing in importance around the world in people's lives and I think that it is inevitable that there will need to be some regulation," Zuckerberg said during testimony before the House Energy and Commerce Committee. "So my position is not that there should be no regulation but I also think that you have to be careful about regulation you put in place."
Larger, more dominant companies like Facebook have the resources to comply with government regulation, he said, but "that might be more difficult for a smaller startup to comply with."
Zuckerberg was answering a question from Eshoo when he informed lawmakers about his personal data, a reference to the Cambridge Analytica scandal that has rocked his company over the past several weeks.
The stakes are high for both Zuckerberg and his company. Facebook has been reeling following revelations last month that the political data-mining firm Cambridge Analytica, which was affiliated with Mr. Trump's 2016 campaign, improperly scooped up data on about 87 million users. Zuckerberg has been on an apology tour for most of the past two weeks, culminating in his congressional appearances this week.
But what comes next is unclear.
Lawmakers said repeatedly they think Facebook should probably be regulated. But there was no consensus at all on that point -- what exactly should be regulated, or even what the biggest problems are.
Members pressed Zuckerberg on the company's privacy policies and often declared that Facebook needs to do more to protect user data. Several lawmakers touted bills they've introduced. But there was no clear thread among them as to how, or if, the government should step in.
Rep. Frank Pallone of New Jersey, the committee's top ranking Democrat, sounded pessimistic that Congress will pass anything.
"I've just seen it over and over again -- that we have the hearings, and nothing happens," Pallone said.
Rep. Greg Walden, R-Oregon, the committee chairman, asked Zuckerberg if it ever crossed his mind several years ago when user data was being extracted from Facebook "that you should be communicating more clearly with users that Facebook is monetizing their data." Information about users "is probably the most valuable thing about Facebook," Walden added.
Zuckerberg said that Facebook allows people to decide whether and how they want their information shared. But he said his company "can do a better job of explaining how advertising works."
After a testy exchange with Zuckerberg, Rep. Diana DeGette, D-Colorado, said Congress should consider imposing "really robust penalties" for social media companies that repeatedly compromise user information.
"We continue to have these abuses and these data breaches," DeGette said. "But at the same time it doesn't seem like future activities are prevented."
During roughly five hours of questioning by members of the Senate Judiciary and Commerce committees on Tuesday, Zuckerberg apologized several times for Facebook failures. He also disclosed that his company was "working with" special counsel Robert Mueller in the federal probe of Russian election interference and said it was working hard to change its own operations in the wake of the Cambridge Analytica revelations.
Seemingly unimpressed, Republican Sen. John Thune of South Dakota said Zuckerberg's company had a 14-year history of apologizing for "ill-advised decisions" related to user privacy. "How is today's apology different?" Thune asked.
As for the federal Russia probe that has occupied much of Washington's attention for months, he said he had not been interviewed by special counsel Mueller's team, but "I know we're working with them." He offered no details, citing a concern about confidentiality rules of the investigation.
Earlier this year Mueller charged 13 Russian individuals and three Russian companies in a plot to interfere in the 2016 presidential election through a social media propaganda effort that included online ad purchases using U.S. aliases and politicking on U.S. soil. A number of the Russian ads were on Facebook.
Zuckerberg said Facebook had been led to believe Cambridge Analytica had deleted the user data it had harvested and that had been "clearly a mistake." He said Facebook had considered the data collection "a closed case" and had not alerted the Federal Trade Commission. He assured senators the company would have handled the situation differently today.
