(CNN) California Sen. Kamala Harris' presidential campaign announced Saturday that it raised $2 million in 24 hours following her breakout moment in Thursday's 2020 Democratic debate.

The donations came from more than 63,000 people -- over half of those, 58%, were first time donors, according to the campaign.

The average contribution was $30, the campaign said.

The campaign said it was its single best fundraising day since Harris launched her bid in January.

"We have momentum," said Lily Adams, Harris' communications director. "After her dominant debate performance, where she proved she is the candidate best suited to prosecute the case against four more years of Donald Trump, supporters across this country are fueling our campaign because they saw her empathy, her passion, and her direct focus on the issues that keep people up at night."

We asked you to support our campaign #ForThePeople and you delivered. In the 24 hours after the #DemDebate, we raised more than $2 million from 63,277 people. I am so motivated and inspired by all of you. Now let's go win this fight. — Kamala Harris (@KamalaHarris) June 29, 2019
