Mica Mosbacher - Adviser to President Trump's 2020 campaign

Stephen Sackur speaks to Mica Mosbacher, Republican strategist and member of the National Advisory Board of Trump 2020. If the normal political rules applied to Donald Trump he would be holed up in the White House in a state of despair. He is at war with Democrats in Congress, the federal government is partially shut down, his relationship with Putin's Russia is under fierce scrutiny, and his standing at home and abroad continues to take a hit. And yet, every day he comes out punching; raising the stakes, not retreating. Is the Trump presidency making America great, or greatly diminished?
