Joe Biden told CNN he was caught off guard and "wasn't prepared" for Sen. Kamala Harris' attack on his record on racial issues and busing.
"I was prepared for them to come after me, but I wasn't prepared for the person coming at me the way she came at me."
In the first Democratic debates, Harris took a targeted shot at Biden touting his work with pro-segregation senators in the 1970s.
She also went after his previous opposition to federally-mandated busing as a tool to integrate schools.
