Joe Biden’s campaign is expected to have raised more than $300 million in August, surpassing the Democratic presidential nominee's previous monthly record for fundraising, The New York Times reported Tuesday.

Two people familiar with the matter told the Times that the Biden campaign’s expected total comes from his campaign and shared committees with the Democratic Party. The majority of the former vice president’s August haul came from online grassroots donors, another person familiar with the figures said.

Sources told the newspaper they did not know the exact amount raised for August or how much higher than $300 million the amount would be.

The Biden campaign did not immediately return a request for comment.

Any total that is more than $300 million would be more than previous monthly fundraising by candidates in both parties. The Times notes the total would be more than what President Trump and Hillary Clinton raised in August 2016 combined.

The amount would surpass what is believed to be the monthly record of $193 million collected for former President Obama’s campaign in September 2008, but there is no formal tracking system, according to the Times.

In July, the president and the Republican National Committee fundraised $165 million, compared to Biden's $140 million. The campaigns indicated that at the beginning of August Trump had more than $300 million in the bank and Biden had $294 million.

The Trump campaign also has not announced its August figures, although it touted raising $76 million during the Republican National Convention last week. The week before, the Biden campaign reported more than $70 million was collected during the Democratic National Convention.

But the Biden campaign announced it earned $48 million in 48 hours after Sen. Kamala Harris (D-Calif.) was named the vice presidential candidate last month, a massive fundraising haul for the Democratic ticket.

Reports of Biden’s August totals come after ActBlue, a website for Democratic donations, reported its second highest fundraising day ever on Monday with more than $35 million donated.

The site has processed at least $11 million every day since Harris was named Biden’s running mate.
