Sen. Kamala Harris continued her steady ascent in the Democratic primary field on Friday as her campaign revealed that she raised nearly $12 million during the second quarter of the year.

The presidential hopeful received donations from more than 279,000 individuals, who donated an average of $39, overall for the quarter, giving the former prosecutor a boost after a fiery exchange with Joe Biden during their first Democratic debate.

Harris’ haul could not top South Bend, Ind., Mayor Pete Buttigieg, 37, whose campaign announced earlier this week that it raked in $24.8 million in the second quarter.

Former vice president Biden has raised $21.5 million for his presidential bid since entering the race on April 25.

Also, Sen. Bernie Sanders collected $18 million in the second quarter.

Harris, the 54-year-old junior senator from California since 2017, came out strong in the Democratic debate on June 27, confronting Biden, 76, on the issue of race, specifically his comments about working with segregationist senators and his past opposition to busing.

“I do not believe you are racist,” Harris, who would be the first African American woman elected president, told Biden. “But I also believe, and it is personal — it was hurtful to hear you talk about the reputations of two United States senators who built their reputations and careers on the segregation of race in this country.”

Harris revealed that, as a child, she had been part of the second class to integrate her public school in California growing up and was bused to school.

Biden said during an interview on CNN Friday that Harris took his position on busing out of context.

“It’s so easy to go back and go back 30, 40, 50 years and take a context and take it completely out of context,” Biden told host Chris Cuomo.

Harris’ debate performance also bolstered her position in the polls, with her receiving a surge of support in surveys taken after the event.

She nearly tripled her standing in a Quinnipiac poll of the Democratic primary race released Tuesday, with 20% support compared with Biden at 22%, his lowest number in a Q poll yet.

Sen. Elizabeth Warren of Massachusetts came in third at 14%, Sanders of Vermont had 13% and Buttigieg got 4%, according to the survey.

That compares to a June 11 poll that had Biden at 30%, Sanders at 19%, Warren at 15%, Buttigieg at 8% and Harris with 7%.
