Booker, the New Jersey senator, made his remark on Sunday in response a question about a contentious exchange between Biden and Kamala Harris at the second debate in Miami.Harris interjected during a discussion of race and policing, noting that as the only black candidate on the stage, she should be able to respond. She then focused on Biden and attacked his record on race.Campaigning recently, Biden warmly recalled his working relationship with segregationist senators. Opponents pressed him to apologize, but he refused.“I do not believe you are a racist,” Harris said on the debate stage, as she looked directly at Biden. “But … it is personal. And it was actually hurtful to hear you talk about the reputations of two United States senators who built their reputations and career on the segregation of race in this country.”Harris also accused Biden – who early in his long political career opposed the federally mandated bussing of students as a way to integrate schools – of propping up policies that would have kept minority students like herself out of majority white districts.“There was a little girl in California who was part of the second class to integrate her public schools, and she was bussed to school every day,” Harris said. “And that little girl was me.”Visibly upset, Biden said “that is a mischaracterization of my position across the board. I did not praise racists. That is not true.”Booker, who is African American, told NBC Biden has “an inability to talk candidly about the mistakes he made, about things he could’ve done better, about how some of the decisions he made at the time in difficult context actually have resulted in really bad outcomes.”He went on: “We have one destiny in this nation and right now the vice-president to me is not doing a good job at bringing folks together. In fact, and I’ve heard this from people across the country, he’s causing a lot of frustration and even pain with his words.”Another candidate, Julián Castro, also weighed in, when asked if he thought Harris’s criticism was “relevant”.“Oh, of course,” Castro, the former San Antonio mayor and US housing secretary, told NBC. “I think it’s relevant. I think the record of all of the candidates that are running, including Vice-President Biden’s record, is relevant and his stance on busing is relevant as well.“What I took as his position being that he allowed local communities to make a decision, essentially relying on states’ rights, I think he’s going to have to continue to explain how that was a good position. Because we’ve had a very painful history in this country of trying to desegregate communities.“That pain is still there in this country, and he’s going to have to address that – not only in the debate, but I think going forward.”
