As President Trump and his allies escalate the administration's battle on colleges, and on Harvard specifically, Steven Levitsky, Harvard professor and author of “How Democracies Die,” joins Christiane to discuss the reshaping of knowledge in America. Then, best-selling German author Daniel Kehlmann speaks with Christiane about his new book “The Director," exploring what it was like for artists like G.W. Pabst who made films for Joseph Goebbels and the Nazis. Marking 600 days of war between Israel and Hamas in Gaza, Christiane highlights both Jeremy Diamond's report on Israel's fight to get back the 58 remaining hostages in Hamas captivity and Oren Lieberman's story on the chaotic aid delivery to starving Palestinians this week. Christiane also talks to Wilfred Frost, son of the legendary TV host David Frost, about his father's iconic interviews with the likes of Richard Nixon, Yasser Arafat and Elton John, and a new documentary series following his storied career. From her archive, Christiane pays tribute to award-winning Brazilian photographer Sebastião Salgado. Finally, marking 45 years since CNN's founding, Christiane revisits her conversation with company founder Ted Turner about how he changed the news business forever.
