Former US President Barack Obama said today that his India visit was part of his single-biggest post-Presidency mission: to help form the next generation of leadership, not only in the US but across the world. Ahead of the event, Ben Rhodes, Mr Obama's Chief International Advisor told NDTV, "He is here to listen and learn from the young leaders about their work and how his foundation can help them. The Obama Foundation hopes to help them to grow their network and promote their work on the digital platform."
