President Biden has set an ambitious goal for the United States to be carbon-neutral by 2050. Achieving it means weaning the country off fossil fuels and using more alternative energy sources like solar and wind. But environmentalists disagree about whether nuclear power should be part of the mix.

Todd Larsen, executive co-director for consumer and corporate engagement at Green America and Meghan Claire Hammond, senior fellow at the Good Energy Collective, a policy research organization focusing on new nuclear technology, join Jane Coaston to debate whether nuclear power is worth the risks.

And then the Times columnist Bret Stephens joins Jane to talk about why he thinks America needs a liberal party.
