Wicked Coin

In this episode of Wicked Coin, Diana Shaw and Tatiana Sainati explore one of the most disturbing healthcare fraud schemes in U.S. history: a trusted oncologist who exploited patients' deepest fears, administering often devastating cancer treatments to people who didn't need them. The result was irreversible harm to hundreds of patients and tens of millions of dollars in fraudulent billings to Medicare. Joined by special guest Christi Grimm, former Inspector General of the U.S. Department of Health and Human Services, Diana and Tatiana take listeners inside the investigation that brought the scheme down – examining the systemic vulnerabilities that enabled this years-long fraud, the tenacious whistleblowers who exposed it, and the remarkable interagency investigative effort that brought a swift end to Dr. Fata's reign of terror. It's a harrowing tale of greed and power, but also one of courage, accountability, and the critical role of oversight in protecting the most vulnerable.

In this episode of Wicked Coin, Tatiana Sainati and Diana Shaw are joined by former government auditor and attorney Dr. J. Kirk McGill, who recounts his firsthand experience uncovering serious flaws in federal grant management. Kirk walks listeners through how questionable accounting practices, conflicted governance, and institutional pressure combined to allow massive spending failures to go unchecked. When his efforts to raise concerns internally were blocked, Kirk made the consequential decision to report what he found—triggering a years long whistleblower battle with real personal cost. The episode explores what it takes to speak truth to power, and what happens when the systems designed to prevent corruption instead work to suppress it.
