It's taken 18 months for a TV reality star to go from laughing-stock to leader of the free world. The BBC’s North America Editor has travelled the length and breadth of the United States, experiencing it from a perspective that most of us could only dream of: he has flown aboard Air Force One, interviewed President Obama and has even been described as ‘a beauty’ by none other than Donald Trump. Sopel sets out to answer our questions about a country that once stood for the grandest of dreams but which is now mired in a storm of political extremism, racial division and increasingly perverse beliefs. Chaired by Jim Naughtie.
