New Jersey Sen. Cory Booker said that people who don’t think nuclear power needs to be part of the fight against climate change -- a group that includes many of his presidential opponents -- “aren’t looking at the facts.”

Booker said that he warmed to nuclear power after reading studies about it and talking to nuclear scientists about technological advancements “that make nuclear safer.”

“People who think that we can get there without nuclear being part of the blend just aren’t looking at the facts,” Booker said.

Vermont Sen. Bernie Sanders and Massachusetts Sen. Elizabeth Warren are both opposed – in different ways – to nuclear power.

Warren said Wednesday that she would oppose nuclear energy as a way to combat climate change should she be elected president in 2020.

“We’re not going to build any nuclear power plants and we’re going to start weaning ourselves off nuclear energy and replacing it with renewable fuels,” Warren said, adding that she hopes to phase out nuclear power by 2035.
