The Trump administration announces plans to drill the Arctic National Wildlife Refuge and the clock ticks down to November 4, the day America looks set to officially leave the Paris Climate Agreement. These moves come in the midst of a presidential election in which climate has played a bigger role than ever before. Former U.S. Secretary of State John Kerry committed America to the Paris Climate Agreement back in 2016 and he joins Christiane Amanpour to discuss the Democratic campaign and share his perspective as someone who went head to head with an incumbent Republican President. Then, this year’s virtual Democratic National Convention is shaping up to be like no other before, but these nominating events have a long history of generating their own magical moments. Our Walter Isaacson talks to Dan Rather, former anchor of the CBS Evening News and Margaret Carlson, columnist at The Daily Beast, about the meaning and purpose of these conventions in the landscape of America’s politics. And Christiane is joined by Democratic Senator Cory Booker to discuss the Biden-Harris ticket and this year’s push for Democratic unity.
