Wylie exposed Cambridge Analytica's role in Brexit and the Trump presidential campaign. Cambridge Analytica collected personal data from millions of Facebook users, and used it to target people susceptible to conspiracy theories and disinformation. Wylie was the research director at Cambridge Analytica, before leaving in protest over the direction it had taken. His new book is 'Mindf*ck: Cambridge Analytica and the Plot to Break America.'
