Tim Walz accepts VP nomination at DNC Day 3

Minnesota Gov. Tim Walz has accepted his party's nomination for vice president. He used his Democratic National Convention address to thank the packed arena for "bringing the joy" to an election transformed by the elevation of his running mate, Vice President Kamala Harris. Democrats gathered at Chicago's United Center are hoping to build on the momentum Harris has brought since taking over the top of the party's presidential ticket last month.
