Tom Vilsack, former Iowa Governor and President Obama's Secretary of Agriculture, has been an important voice in VP Joe Biden's 2020 presidential campaign. In an interview with Ian Bremmer for GZERO World, Vilsack shares some of the conversations he's had with Biden about the importance of the rural vote and caring about issues that impact the heartland. He also discusses the need for empathy at a time when so many Americans are suffering, and his take on why President Trump hasn't expressed much of that sentiment.
