Former Vice President Joseph R. Biden Jr., who has battled with Senator Elizabeth Warren of Massachusetts in the past over the issue of bankruptcy, now supports a plan by Ms. Warren to make changes to the bankruptcy system, his presidential campaign confirmed on Saturday.
Mr. Biden would work toward putting in place her bankruptcy plan as president, and he could address the issue at greater length in Sunday night’s debate, Biden advisers said.
It is the latest sign that Mr. Biden, fresh off a string of victories, is looking for ways to engage younger and more liberal voters who have remained skeptical of his candidacy, and it reflects a recognition among his allies that he will need enthusiastic support from progressives in a general election should he become the Democratic nominee.
The move also comes amid speculation over whether Ms. Warren, who dropped out of the race this month, will issue an endorsement of Mr. Biden or of Senator Bernie Sanders of Vermont, his chief rival for the nomination, or whether she sits out the primary entirely.
“I’ve endorsed Elizabeth Warren’s bankruptcy proposal, which in fact goes further, allows for student debt to be relieved in bankruptcy,” Mr. Biden said in a virtual town-hall-style event on Friday night as he talked about the importance of the ability to access education. He added that that was a possible area of agreement with Mr. Sanders.
The clash between Ms. Warren and Mr. Biden over the nation’s bankruptcy system took place more than a decade ago, when Ms. Warren was a Harvard law professor and Mr. Biden was a senator from Delaware. Ms. Warren was a vocal opponent of a 2005 bankruptcy overhaul that Mr. Biden supported. The bankruptcy legislation ultimately passed and was signed into law by President George W. Bush.
On the day Mr. Biden entered the presidential race last year, Ms. Warren jabbed him over the issue, saying that he had sided with the credit card companies when she was fighting for consumers.
In January, as a presidential candidate, Ms. Warren laid out a plan to roll back provisions in that bill, which she said was “terrible for families in need.” Her plan seeks to make it easier for people to go through the bankruptcy process, and it would allow student loans to be discharged in bankruptcy like other debts.
Mr. Biden’s remark about endorsing the bankruptcy plan came in response to a question about what he would do to engage supporters of Mr. Sanders. The two men will face off one-on-one in a debate on Sunday.
“Bernie and I agree on a whole range of issues,” Mr. Biden said, pointing to subjects including climate change and education, and stressing his willingness to support Mr. Sanders if he is the nominee. Mr. Biden said he also hoped that the choice would be “a matter of alternatives.”
“You know, you may not agree with every detail that I propose, but the fact is that it’s awfully difficult to conclude that I’m anywhere near Donald Trump,” he said.
