Michael Lewis on Donald Trump

David and Helen talk to bestselling author Michael Lewis about the effect that Trump's presidency is having on the workings of the US government and the risks we are all running as a result. From wilful ignorance to breathtaking corruption, we explore the different ways that one man can change the character of an entire political system. Plus we ask what, if anything, can be done about it. https://bit.ly/2M1yzVk
