UNDATED (AP) — Joe Biden says his comments about working successfully with segregationist senators in the past were meant to argue that leaders sometimes have to work with people they disagree with to get things done. Several Democratic presidential rivals have criticized him over the remarks. Kamala Harris says the former vice president is “coddling” segregationists in a way that she believes suggests he doesn’t understand the nation’s history. Biden points to his record on civil rights in his defense.
