Desegregation busing

The senator made waves at the first Democratic presidential debates by going after Biden's record on school desegregation.
Former Vice President Joe Biden defended his civil rights record a day after fellow Democratic presidential candidate Sen. Kamala Harris (D-Calif.) criticized both his attitude towards segregationist senators and his past opposition to school busing.
As Joe Biden considers a run for president, his long history in the Senate continues to come under scrutiny.
