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 that have occurred 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" that has been 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. New CIA director William Burns tells Pelley why it has been difficult finding answers. Click here to read more and watch a preview. Michael Rey and Oriana Zill de Granados are the producers.
