Zuckerberg tells House panel his own data was shared by Cambridge Analytica

Zuckerberg returned to the Capitol after enduring hours of questioning in a Senate hearing Tuesday where he defended the social network's value and pledged to correct its mistakes

Facebook CEO Mark Zuckerberg says his Facebook data was included in the personal information sold to malicious third parties, a reference to the Cambridge Analytica scandal that has rocked his company over the past several weeks.

Facing his second day of questioning from members of Congress on Wednesday, Zuckerberg was answering a question from Rep. Anna Eshoo, a Democrat from California.

Facebook has said that 87 million people's personal data was scooped up when some 270,000 users took a personality quiz and had not just their data, but the data of their friends to be accessed by an outside app.
