Commemorations are being held to mark 80 years since the liberation of the Auschwitz death camp by Soviet troops. A few of the remaining survivors warned of the rising antisemitism and hatred they are witnessing in the modern world during a ceremony that was held on Monday at the site of the camp, which Nazi Germany set up in occupied Poland during World War Two to murder European Jews on a massive scale. We spoke with Ambassador Deborah Lipstadt who served as Special Evoy to Monitor and Combat Antisemitism and currently is a professor of history and religious studies at Emory University. Also, a conversation with Leah Wolfson Director of Academic Programs with the United States Holocaust Museum
