Facebook CEO Mark Zuckerberg began a two-day congressional inquisition on Tuesday.
Zuckerberg opened his remarks before the Senate Commerce and Judiciary committees by taking responsibility for failing to prevent Cambridge Analytica, a data-mining firm affiliated with Donald Trump’s presidential campaign, from gathering personal information from 87 million users to try to influence elections.
Zuckerberg had apologized many times already, to users and the public, but this was the first time in his career that he had gone before Congress. He also testified Wednesday before the House Energy and Commerce Committee.
