Investigative reporters at ProPublica chase down evidence of wrongdoing and bring it to light. That evidence can be on paper — or on thumb drives, in secret recordings, from conversations with whistleblowers. Each episode, you’ll ride along as we talk to reporters and their sources, uncover hidden facts and show you the receipts. When we publish what we find, things can change. Laws are passed, corrupt leaders fall, innocent people walk out of prison and sometimes a life is even saved. Investigative reporter Jessica Lussenhop is your guide.
