Joe Biden on His Ongoing Feud with Bernie Sanders: ‘Calm Down, It’s Okay’

O'KEEFE: "Yesterday, you said you accepted Bernie's apology, now you're attacking him. Why are you doing that? Why wasn't his apology enough, Mr. Vice President? Why attack Sanders?"
BIDEN: "Why, why, why, why, why, why, why? You're getting nervous, man! Calm down, it's okay. He apologized for saying that I was corrupt. He didn't say anything about whether or not I was telling the truth about Social Security."
