Watch: Facebook CEO Mark Zuckerberg’s testimony before House committee

Facebook CEO Mark Zuckerberg will testify in front of the House of Representatives Committee on Energy and Commerce beginning at 10 a.m.

During a nearly five hour testimony Tuesday during a joint hearing of the Senate Judiciary and Commerce Committees, Zuckerberg apologized several times for Facebook’s privacy failures.

Lawmakers were at times aggressive Tuesday as they accused Zuckerberg of failing to protect the personal information of millions of Americans from Russians intent on upsetting the U.S. election.

Zuckerberg disclosed that his company is “working with” special counsel Robert Mueller in the federal probe of Russian election interference. He says it’s working hard to change its own operations after the harvesting of users’ private data by a data-mining company affiliated with President Donald Trump’s campaign.
