Meet Brittany Kaiser, Cambridge Analytica Whistleblower Releasing Troves of New Files from Data Firm

New details are emerging about how the shadowy data firm Cambridge Analytica worked to manipulate voters across the globe, from the 2016 election in the United States to the Brexit campaign in Britain and elections in over 60 other countries, including Malaysia, Kenya and Brazil. A new trove of internal Cambridge Analytica documents and emails are being posted on Twitter detailing the company's operations, including its work with President Trump's former national security adviser John Bolton. The documents come from Cambridge Analytica whistleblower Brittany Kaiser, who worked at the firm for three-and-a-half years before leaving in 2018. We speak with Jehane Noujaim and Karim Amer, co-directors of the Oscar shortlisted documentary "The Great Hack"; Brittany Kaiser, the Cambridge Analytica whistleblower featured in "The Great Hack" and author of "Targeted: The Cambridge Analytica Whistleblower's Inside Story of How Big Data, Trump, and Facebook Broke Democracy and How It Can Happen Again"; and Emma Briant, a visiting research associate in human rights at Bard College whose upcoming book is titled "Propaganda Machine: Inside Cambridge Analytica and the Digital Influence Industry."
