In its follow up answers for the questions asked during data scandal testimony, Facebook has claimed CEO Mark Zuckerberg wasn't aware that British firm Cambridge Analytica may not have deleted users' data until March 2018. Facebook earlier claimed Analytica assured it that its users' data was deleted in 2015. Analytica was accused of illegally harvesting data of 87 million users.
