Sen. Bernie Sanders has confirmed to VPR that he is seeking the 2020 Democratic presidential nomination. His official announcement video is expected to stream online Tuesday morning. "I wanted to let the people of the state of Vermont know about this first," Sanders told VPR's Bob Kinzel. "And what I promise to do is, as I go around the country, is to take the values that all of us in Vermont are proud of — a belief in justice, in community, in grassroots politics, in town meetings — that's what I'm going to carry all over this country."
