Former Democratic presidential primary rival Sen. Elizabeth Warren helped Joe Biden to acquire a record amount through a virtual fundraiser. The former vice president's campaign announced that the presumptive Democratic presidential nominee hauled in a whopping  $6 million from 620 donors through an online fundraiser.

This is the largest haul for the Biden Victory Fund until now. The Biden Victory Fund alludes to a joint fundraising operation created by the Biden campaign and the Democratic National Committee's joint efforts in April. Biden thanked Warren for asking her friends to help him out, adding that it is the biggest fundraiser they have ever had.

Aside from Warren, the event was hosted by National Center for Learning Disabilities board member Shanti Fry and retired software entrepreneur Paul Egerman. After the fundraiser came to an end, the campaign revealed that Biden will collaborate with his former boss Barack Obama for a virtual fundraiser next week.

Slated to take place on June 23, the upcoming event that will target small donors marks Obama's foray into fundraising for his former vice president. The invitations, shared via a tweet, states that those interested can chip in any amount to attend their grassroots fundraiser.

The Biden campaign's event with Warren focused on top-dollar donors, with tickets retailing from $250 to $100,000. The former vice president's campaign's fundraising with Elizabeth Warren comes as the senior United States Senator from Massachusetts is touted as one of the contenders to be Biden's running mate.

The fundraising event took place three days after a group comprising over 100 progressive activists as well as celebrities including Jane Fonda, who sent Biden a letter to choose Warren as his pick for the Democratic Party’s 2020 vice presidential nominee.

Recalling Warren’s track record and how she fearlessly tackled Wall Street and pushed pro-worker policies, Biden noted that they have a similar goal of building a stronger more resilient middle class. The former vice president said he and Warren believed that Wall Street didn't build America, adding that its cause of their time to create a more resilient middle class without leaving people behind.

Biden said they do not support the abuse of power. Warren isn't even close to the first former 2020 Democratic presidential nomination rival who collaborated with Biden to raise a considerable amount of money since he was selected as the party’s presumptive presidential nominee. California's Sens. Kamala Harris, Minnesota's Amy Klobuchar, New Jersey's Cory Booker, and former South Bend, Ind., Mayor Pete Buttigieg have all co-hosted events to raise funds with Biden in the past couple of months.
