Kamala Harris actually said...
We are a diverse country, yes. And some people would suggest that in diversity when there is a diverse population one cannot achieve unity. I reject that notion because this is my belief. Yes, we are diverse and we have so much more in common than what separates us. And when we emphasize that commonality, when we recognize that commonality, we will achieve greater unity.
