Does Kamala Harris have enough momentum to make it through to election day? We speak to Democratic Senator for Maryland, Chris Van Hollen to get his take on her position on China, Gaza and the US economy. Also on the programme: we ask what it means to be on Russia's most-wanted criminal list; and we hear about the world’s second largest diamond found in Botswana.(Photo: Democratic presidential candidate and U.S. Vice President Kamala Harris in Chicago, Illinois Credit: REUTERS/Mike Segar)
