Volodymyr Zelensky emerged on the scene in 2019 when he was elected president of Ukraine. Now he is embroiled in American domestic politics as his phone call with President Trump is at the center of the impeachment inquiry currently taking place in Congress. Cnaan Liphshiz, European news reporter for JTA, breaks down who Volodymyr Zelensky is, where Ukraine is headed, and what the controversial call means. Then we are joined by NYU Professor of History Edward Berenson to examine how an incident of a missing child led to America's only blood libel case. Finally, ahead of Yom Kippur, The Times of Israel's Jewish Times Editor Amanda Borschel-Dan takes listeners on a journey to Israel's National Library, where Dr. Gila Flam, director of the Music Department of the National Library, helps us delve into the emotional pull and significance of Kol Nidre, an ancient Ashkenazi musical setting of a prosaic Aramaic vow of renunciation.
