Erica Meier, the executive director of Compassion Over Killing, who attended Booker's swearing-in ceremony Tuesday, said the senator's outlook is inspirational, not extremist.
"It's not extreme to care about your health, and it's not extreme to care about animals," Meier told The Dodo. "When I think about what's extreme, I think about the cruelty being uncovered in factory farms - that, to me, seems extreme."
While waiting to meet Booker, Meier said she met a number of people who were going vegan because Booker inspired them.
"He's really inspiring people to want to make changes that are improving their health - as well as helping animals and helping the environment," she said.
