Senator Sherrod Brown reveals how he first learned about the rich history of his desk in the U.S. Senate and how he grappled with some of the contradictions and controversies of the men who sat there before him.  We discuss the singing cowboy turned one term Senator from Idaho who once spent a night in Bull Conner’s jail in Alabama and the Senator from Wisconsin who was a legendary penny pincher and never missed a vote.  He talks about getting back to a more movement-oriented definition of Progressivism, his belief in the dignity of work, and why he feels it’s a winning message for Democrats running against President Trump in 2020.  Plus Senator Brown opens up about his decision to stay out of the Democratic Presidential Primary, whether or not he might reconsider that choice in light recent calls for him to jump into the race, and how he plans to approach a potential impeachment trial in the U.S. Senate.
