Ex-Cambridge Analytica staffer: "There were more" apps collecting user data Brittany Kaiser, a former official at Cambridge Analytica, is sharing what she considers some of the data firm's questionable practices. The British-based company processed data for several Republican clients including Donald Trump's presidential campaign. It drew attention when it was revealed the company harvested data from 87 million unknowing Facebook users, and cameras caught its CEO discussing underhanded tactics. Kaiser tells "CBS This Morning" co-host John Dickerson she wants to speak out now about what she sees as the "wild west" attitude of data gathering.
