Ten of the leading 2020 Democratic candidates are set to appear in a lengthy session focused on the "climate crisis" and spanning seven hours, with each of the candidates allotted roughly 40 minutes. The town hall is taking place on Wednesday night.
The participants include former Housing and Urban Development Secretary Julián Castro; businessman Andrew Yang; Sen. Kamala Harris, D-Calif.; Sen. Amy Klobuchar, D-Minn.; former Vice President Joe Biden; Sen. Bernie Sanders, I-Vt.; Sen. Elizabeth Warren, D-Mass.; South Bend, Ind., Mayor Pete Buttigieg; former congressman Beto O'Rourke; and Sen. Cory Booker, D-N.J.
Appearing on CNN's "New Day," Weir explained why the network was pursuing a climate-focused event with the presidential hopefuls.
"There was so much cry out from those voters who will caucus for Democrats or independents who put this topic at the very top of their concern list," Weir said. "And many were calling for a dedicated climate debate with all 10 on stage. The DNC didn’t go for that for whatever reason. And so we thought: 'Why don't make it happen?'"
He continued: "Look, I’m biased. I think we could do a town hall a day on this and it wouldn’t be enough to cover it because it’s everything. It’s everything in our lives, from energy to politics to geopolitics to psychology to history."
Weir will appear alongside CNN anchors Anderson Cooper, Chris Cuomo, Don Lemon, Erin Burnett, and Wolf Blitzer throughout the night.
