Joe Biden is still trying to put the busing dispute with Senator Kamala Harris behind him. Today in his first big interview since last week’s debates the former vice president admitted, “I wasn’t prepared for the person [Harris] coming at me the way she came at [me], she knows Beau, she knows me.”

“It’s so easy to get back and go back 30, 40, 50 years and take a context and take it completely out of context. I get all this information [about] other people’s past and what they’ve done and not done and I’m just not going to go there,” Biden added.

During the CNN interview, Chris Cuomo asked Biden: “how can Democrats have confidence that you can take on the biggest and baddest when you have problems sparring?” Biden shot back that Trump is a different story, “the idea that I’d be intimidated by Donald Trump … he’s the bully that I knew my whole life, he’s the bully I’ve always stood up to.”
