Facebook CEO Mark Zuckerberg was asked if his company tracks private browsing data, even after the user logs off of Facebook.

He couldn’t answer the question.


Republican Mississippi Sen. Roger Wicker asked, “There have been reports that Facebook can track a user’s internet browsing activity even after that user has logged off of the Facebook platform. Can you confirm whether or not this is true?”

“Senator, I want to make sure I get this accurate,” Zuckerberg said. “So, it would probably be better to have my team follow up.”

“You don’t know?”

“I know that people use cookies on the Internet,” Zuckerberg said. “And that you can probably correlate activity between sessions. We do that for a number of reasons, including security and including measuring ads to make sure that the ad experiences are the most effective, which of course people can opt out of. But, I want to make sure that I’m precise in my answer so let me follow up on that.”
