Appearing on CNN, Biden was pressed about his ability to stand up to Trump following a debate last week in which Sen. Kamala D. Harris (D-Calif.) aggressively questioned Biden’s opposition to federally mandated busing in the 1970s, appearing to catch him off guard.

“The idea that I’d be intimidated by Donald Trump — he’s the bully that I knew my whole life,” Biden said. “He’s the bully that I’ve always stood up to. He’s the bully that used to make fun when I was a kid that I stutter, and I’d smack him in the mouth.”
