Hillary Clinton defended herself after 2020 Democratic presidential contender Pete Buttigieg criticized his party’s 2016 nominee for being too hopeful and not understanding the struggles of everyday Americans.

“I really do believe that we always have to appeal to our better selves because the wolf is at the door, my friends,” Clinton said Friday during an appearance at the 10th Annual Women in the World New York Summit. “Negativity, despair, anxiety, resentment, anger, prejudice, that’s part of human nature and the job of the leader is to appeal to us to be more than we can be on our own, to join hands in common effort.”
