Sen. Warner: Mark Zuckerberg Needs to Testify Before Congress

Facebook CEO Mark Zuckerberg should testify before Congress about privacy protections in the wake of revelations data from 50 million users was shared without their knowledge, Sen. Mark Warner, D-Va., said Sunday.

In an interview on CBS's "Face the Nation," Warner said Zuckerberg has to go beyond the full-page ad he placed in British and U.S. newspapers, including The New York Times, The Washington Post, and The Wall Street Journal, to apologize for the Cambridge Analytica scandal.

"I think Mr. Zuckerberg needs to come and testify before Congress, not just put an advertisement in a newspaper," he said, adding: "He needs to come . . . and explain how they're going to work with us to both protect privacy through 50 million Facebook accounts that were used by this sketchy firm Cambridge Analytica."

The firm obtained information from as many as 50 million Facebook profiles by abusing its data-sharing features.

"There's something a little fishy about this firm," Warner said. "We now know that the CEO reached out to Julian Assange, the Wikileaks leader, about hacked emails, to work with a Russian oil company who was looking about election data in America."

Warner said questions about the extent of the firm's role in the campaign of President Donald Trump show "why [the Senate Intelligence Committee] investigation needs to continue and the [special counsel Robert] Mueller investigation needs to continue."
