Since announcing his candidacy, Joe Biden received the most campaign donations in an hour during Saturday's Philadelphia rally, raising more than $1,000 per minute, campaign officials said Tuesday.

Two-thirds of all its donors were new to the campaign's list and about 97 percent of all donations were under $200, campaign officials said.

More than 8,000 teachers and educators have donated to the campaign, which is the largest number of any occupation.

In the first 24 hours of his campaign, Biden raised $6.3 million dollars — the most of any of his Democratic opponents. Of those donations, 65,000 donations came from people who were not on any existing email lists.

Unlike other candidates, Biden has not shied away attending fundraisers hosted by wealthy Democrats. The ability to raise a significant amount of money to run an expensive campaign was among the former vice president's key considerations as he weighed a presidential bid.

Biden has previously said that he will not take money from Super PACS or registered lobbyists.
