Joe Biden raised $21.5 million, trailing behind Pete Buttigieg's $24.8 million

But Biden raised more money per day than any other Democrats.

Biden's total trail behind South Bend, Indiana, Mayor Pete Buttigieg's $24.8 million haul this quarter, but the Biden campaign emphasized that the former vice president raised more money per day this quarter than any Democratic candidate, given that his total comes from just the first 66 days of his campaign, compared to the entire 90-day period Buttigieg had to raise money this quarter.

Biden's campaign also highlighted that it had raised $6.3 million in its first 24 hours, more than what any other presidential campaigns had raised in the same time period.

According to the campaign, 97% of the donations were from grassroots supporters who gave less than $200. More than 256,000 donors gave over 435,000 donations and the average donation was $49.

The campaign also reiterated that Biden has not accepted any donations from federally registered lobbyists, corporate PACs and fossil fuel executives as many other candidates have pledged.

A series of 2020 presidential hopefuls have announced their second quarter fundraising figures since Buttigieg kicked off with his haul earlier this week. Sen. Bernie Sanders, I-Vt., announced his campaign had raised $18 million from contributions and Sen. Michael Bennet, D-Colo., raised $2.8 million. The Trump campaign also announced that, with the Republican National Committee, it had raised a total of $105 million for the president's re-election bid.
