What, if anything, can be accomplished in Davos?

Ukraine’s First Lady Olena Zelenska opened the World Economic Forum in Davos, Switzerland today with a stark warning about the horrors and mass killings her people are facing. The war is the number one topic at the summit, though leaders will also discuss climate change and the cost-of-living crisis. But will the forum be more than just a talking shop? One voice in attendance carries a lot of weight: European Commission President Ursula von der Leyen, who was recently named the most powerful woman in the world by Forbes Magazine. She joins Christiane from Davos. 

Also on today's show: Hina Rabbani Khar, Pakistani Minister of State for Foreign Affairs; Joe Berlinger, Director, Madoff: The Monster of Wall Street.
