WASHINGTON -- Facebook CEO Mark Zuckerberg is testifying for the first time ever before Congress on Tuesday as he attempts to apologize for high-profile privacy breaches at the social media giant and convince doubtful lawmakers that he can fix the problem without government intervention. Zuckerberg is trying to restore public confidence after recent revelations that data from up to 87 million Facebook users was shared with Cambridge Analytica, a data mining firm used by the Trump campaign in the 2016 election. The information was shared without users' knowledge.
