It's fair to say that there has been quite limited division during this administration among Democrats. What are you Joseph Biden and Connolly Harris need to do to bring the Democratic Party back together. I think our unity is our greatest strength and I think Amy it's been. In.

Every single candidate has come together in a full throated fashion behind Joseph Biden and now com what Harris. NN that is indeed our greatest strength we're practicing the politics. Did this the the arithmetic is what it's all about politics we are adding to our base Joseph Biden. He attracts hardcore Democrats independents.

We have heard from progressives. Within your party who have expressed some skepticism some doubt. About Connell Harris and they've said that she is to law and order that she's too cozy. With the police that she's too much of a centrist what do you say to those critics. I think look at the facts that Connell Harris is a fighter she took on a big banks and California got a twenty billion dollar settlement for. Victims of mortgage fraud she was the first person she ran the Department of Justice in California the only Department of Justice bigger than that. Is the United States department of justice and she may she undertook major reforms there including the use of body cameras. To make sure that law enforcement was transparent. Her entire life has been fighting for the underdog and I think as the American people get to know her they're gonna see somebody who has their back on the issues that matter most. And I'm so proud to have her on the ticket. And I think people the more you learn about come on Harris the more you will her.
