James Eastland and Georgia Sen. It's much worse than that. Mr Biden's campaign have yet to comment on why it would be unusual for the former senator to not call Mr Biden - who is white - "boy".
"Those were two racist members of the United States Senate", King said. "Remember? Joe Biden comes out, 'Well, if you elect me president, I'm going to cure cancer.' Wow, why the hell didn't you do that over the last 50 years, Joe?"
Biden's comment came in response to a question from MSNBC's Joy Reid, who asked how Biden would overcome the opposition to almost all Democratic ideas during former President Barack Obama's tenure from Senate Majority Leader Mitch McConnell, R-Kentucky. That happened when Biden said he still backed the Hyde Amendment, which prohibits federal funding of abortion, and then, faced with the fury of abortion rights activists, flipped his position. "He repeatedly demonstrates that he is out of step with the values of the modern Democratic Party", de Blasio tweeted Wednesday. "We don't talk to each other anymore", he said. "That's why I've worked so hard in my career to make sure that - I promise you if I'm elected president, you're going to see the single most important thing that changes America, we're going to cure cancer".
De Blasio, who is married to a black woman, tweeted a reference to a handbill circulated by Eastland supporters at his rallies which twisted the Declaration of Independence to say that "whites are created with certain rights, among them are life, liberty, and the pursuit of dead n--rs".
Booker also criticized Biden for his use of the word "boy" - a term that was frequently used by racists to demean black men.
Clyburn said his own work with the late South Carolina Sen.

Trump's comments came in an interview with Time magazine Monday. Their demurrals should be taken with a major grain of salt. Earl Brown said in the statement .
Biden and five other Democrat candidates also ranking high in a potential matchup with Trump. Biden leads 91 - 3 percent among Democrats and 54 - 32 percent among independent voters. He pointed to two segregationists from the South who were serving in the Senate when Biden was elected - Democratic Senators James Eastland of MS and Herman Talmadge of Georgia.
"I'm disappointed that he hasn't issued an immediate apology for the pain his words are dredging up for many Americans".
Biden touted the cooperation and cordiality of a bygone era during a NY fundraiser Tuesday - including with avowed segregationists who helped stall civil rights legislation in the Senate.
Perhaps Rolling Stone senior writer Jamil Smith put Biden's comments from Tuesday night in perspective best when he suggested the former vice president could be taking Black voters for granted.
Biden made the comments as a way to stress the need "to reach consensus under our system" - but ended up pointing to one of the most divisive political struggles in the nation's history.
