Politico's Pulse Check

In 2015, the Wall Street Journal's John Carreyrou revealed that the blood tests developed by Theranos — the $9 billion company led by Elizabeth Holmes — didn't work. Now John's out with "Bad Blood: Secrets and Lies in a Silicon Valley Startup," a book that offers new details about Holmes, her fraud and her efforts to kill his investigation. John joined POLITICO's Dan Diamond to discuss how he got the story and walk through the Theranos timeline (starts at the 1:35 mark), how Holmes was able to attract staff, investors and media attention (12:00), why government regulators didn't spot the fraud (21:30), why staff were scared to blow the whistle (28:15), what Carreyrou thinks of reporters who missed the story and more on his journalistic process (33:30). At the end, there's a lighting round of listener-submitted questions at 43:30. We'd appreciate your help: Please share PULSE CHECK and rate us on your favorite podcast app!
