Facebook CEO Mark Zuckerberg is set to testify today on Capitol Hill amid the burgeoning scandal about how the voter-profiling company Cambridge Analytica harvested the data of up to 87 million Facebook users, without their permission, in efforts to sway voters to support President Donald Trump. On Monday, Zuckerberg met with leaders of the Senate Commerce Committee and Senate Judiciary Committee to express his regrets about Facebook’s mishandling of user data. The company has also unveiled new privacy tools ahead of Zuckerberg’s testimony today. We’ll have more on Facebook later in the broadcast.
