The Betrayal – 60 MINUTES reveals new findings from an unprecedented investigation into the seven-decade-old mystery of how the Nazis discovered Anne Frank, her family, and four others hiding in an Amsterdam annex. Otto Frank, Anne's father, the only family member to survive the Holocaust, returned from Auschwitz with a question: Who betrayed their hiding place to the Nazis? Two inquiries by the Dutch police and decades of research have resulted in theories but no definitive answers. In 2016 a team of investigators and researchers, led by former FBI agent Vince Pankoke, launched a new effort to crack this cold case using modern investigative techniques and technology. Jon Wertheim speaks with Pankoke and others on the team about their groundbreaking approach to this stubborn question, revealing their prime suspect. This is a two-part report.

Targeting Americans – For the past six years, U.S. diplomats stationed in foreign countries have been reporting a series of neurological symptoms, now known as "Havana Syndrome." Scott Pelley reveals new reports of incidents on U.S. soil in a two-part story airing Sunday. High-ranking Homeland Security officials in the Trump administration say they were overcome with feelings of vertigo, confusion, and memory loss while on White House grounds and in their Washington, D.C.-area homes. The incidents and symptoms they describe are similar to the "Havana Syndrome" reported by American diplomats in foreign countries since 2016. The officials spoke to Pelley for Sunday's report. Other stories of officials being stricken were corroborated by former national security adviser John Bolton, who fears there is a threat to the highest levels of the U.S. government.
