Sen. Kamala Harris raised $2 million in 24 hours after her first presidential debate, her biggest fundraising day of the campaign, her campaign said Saturday.

Donations flowed to Harris from 63,277 people, nearly 60 percent of which were first-time donors. The average donation was $30. Her previous largest day was $1.5 million after launching.

Harris’ haul comes in the final days of the second fundraising quarter. She also is holding five fundraisers over the weekend in Los Angeles and San Francisco.
