Harris pushes back on criticisms of her record as a prosecutor

Why it matters: Harris was criticized by some previously for stances including defending the death penalty despite being personally against it, opposing a bill that would've required her office to investigate police shootings and for remaining silent on several criminal justice reforms championed by progressives.

The big picture: In her speech, Harris sought to justify previous policy decisions, rather than apologize for them, according to Politico. And she spoke of her experience as a biracial woman involved in making decisions on how criminal cases were prosecuted, per the LA Times: "We always have to be in those rooms, especially and even when there aren’t many like us there," she said.

"In this election, regarding my background as a prosecutor, there have been those who have questioned my motivations, my beliefs and what I’ve done. But my mother used to say you don’t let people tell you who you are. You tell them who you are. Let me be clear — self-appointed political commentators do not get to define who we are and what we believe. I take my mother’s advice."
