当副总统乔·拜登在2013年宣誓伊丽莎白·沃伦进入参议院时，他告诉她，“你给了我地狱”，指的是她反对他作为参议员在2005年支持的最终通过的破产法案。沃伦笑了。
9月12日，领先的拜登和最近民调中唯一取得实质性进展的民主党人沃伦将在2020年休斯顿的辩论舞台上首次交锋。在长达三个小时的10名候选人辩论阶段，他们是否互相批评，批评的力度如何，还有待观察。但是周三在南卡罗来纳州的一次竞选活动后，拜登放弃了对沃伦的抨击。
“我只是我自己。她就是她，”拜登说。“让人们做出自己的判断。我非常尊敬她。”
他补充道:“我期待着去一个地方——假设我还在——让更少的人参与进来，这样我们就可以进行更多的讨论，而不是一分钟的断言。”
沃伦的竞选团队没有立即回应记者的置评请求新闻周刊周四关于这场比赛，他拒绝对政治报发表评论。
然而，在4月的集会之后，沃伦猛烈抨击拜登，并谈到了他们过去的冲突。
沃伦说:“当这个国家最大的金融机构试图给数百万因医疗问题、失业、离婚和家庭死亡而破产的勤劳家庭施压时，没有人能为他们辩护。”。“我参与了这场斗争，因为他们没有任何人，乔·拜登站在信用卡公司一边。”
她总结道，“这都是公开的记录。”
拜登支持巴拉克·奥巴马总统任命沃伦为总统助理，成立消费者金融保护局。
但沃伦在其他问题上与拜登意见不一，包括她是2016年投票反对一项医疗保健法案的少数参议员之一，该法案为一项癌症“兼职”计划提供资金，该计划以拜登的儿子的名字命名，他的儿子前一年死于脑癌。
2013年1月3日，在华盛顿特区美国国会大厦的旧参议院会议厅，参议员伊丽莎白·沃伦(左)与丈夫布鲁斯·曼和副总统乔·拜登一起参加了一场重演的宣誓仪式。当天早些时候，拜登在当前参议院会议厅的地板上为新当选和再次当选的参议员宣誓就职。
拜登的竞选团队没有立即回应记者的置评请求新闻周刊在他即将面对沃伦的时候。拜登竞选发言人安德鲁·贝茨和前副总统一样，在对政治杂志的评论中没有批评沃伦。
贝茨说:“正如乔·拜登自己所说，他非常尊重伊丽莎白·沃伦。”。“他的竞选活动并不专注于与任何其他候选人竞争，而是证明他有着无与伦比的进步变革记录，是击败唐纳德·特朗普和他所代表的残暴价值观的最佳人选。”
JOE BIDEN SAID 'YOU GAVE ME HELL' TO ELIZABETH WARREN, SHIES AWAY FROM ATTACKING HER BEFORE DEMOCRATIC DEBATE
When then-Vice President Joe Biden swore Elizabeth Warren in to the Senate in 2013, he told her, "You gave me hell," referring to her opposition to a bankruptcy bill he supported as a senator in 2005 that ultimately passed. Warren laughed.
On September 12, Biden, the front-runner, and Warren, the only Democrat to make substantial gains in recent polls, will face off for the first time on a 2020 debate stage in Houston. It remains to be seen if and how hard they criticize each other on the three-hour, 10-candidate debate stage. But after a campaign event in South Carolina on Wednesday, Biden backed off taking hits on Warren.
"I'm just gonna be me. And she'll be her," Biden said. "Let people make their judgments. I have great respect for her."
He added: "I'm looking forward to getting to the place — assuming I'm still around — that it gets down to a smaller number of people so we can have more of a discussion instead of one-minute assertions."
Warren's campaign did not immediately respond to a request for comment from Newsweek on Thursday regarding the matchup, and declined to comment to Politico.
After a rally in April, however, Warren slammed Biden and touched on their past clashes.
"At a time when the biggest financial institutions in this country were trying to put the squeeze on millions of hardworking families who were in bankruptcy because of medical problems, job losses, divorce and death in the family, there was nobody to stand up for them," Warren said. "I got in that fight because they just didn't have anyone and Joe Biden was on the side of the credit card companies."
She concluded, "It's all a matter of public record."
Biden supported President Barack Obama when he appointed Warren as a presidential aide to start the Consumer Financial Protection Bureau.
But Warren has disagreed with Biden on other matters including when she was one of only a few senators in 2016 to vote against a health care bill with funds for a cancer "moonshot" initiative named after Biden's son who died of brain cancer the prior year.
Senator Elizabeth Warren (D-MA) (L) participates in a reenacted swearing-in with her husband Bruce Mann and Vice President Joe Biden in the Old Senate Chamber at the U.S. Capitol January 3, 2013 in Washington, D.C. Biden swore in the newly-elected and re-elected senators earlier in the day on the floor of the current Senate chamber.
Biden's campaign did not immediately respond to a request for comment from Newsweek on his upcoming face off with Warren. Biden campaign spokesman Andrew Bates, like the former vice president, refrained from criticizing Warren in a comment to Politico.
"As Joe Biden said himself, he has deep respect for Elizabeth Warren," Bates said. "His campaign is not focused on running against any of the other candidates, but on making the case that he has an unparalleled record of delivering progressive change and that he is the best person to defeat Donald Trump and the atrocious values he represents."
