Democratic presidential contender Sen. Elizabeth Warren raised $19.1 million during the three-month period that ended in June, her campaign said Monday.
The haul puts the Massachusetts liberal toward the front of the crowded pack of Democrats vying for their party's nomination.
Among candidates who have disclosed their second quarter fundraising numbers, Warren lags only South Bend, Indiana, Mayor Pete Buttigieg and Joe Biden, the former vice president. Sen. Bernie Sanders of Vermont trailed Warren, raising $18 million, according to his campaign. Sen. Kamala Harris of California raised $12 million.
Warren's campaign said its average donation amount was $28.
"Our movement is powered solely by grassroots donors: Since we launched, more than 447,000 donors have made nearly 900,000 donations to power this campaign," the campaign wrote in a post on Twitter. "We're building something incredible together. Thank you for being a part of it."
Warren has said she will not accept donations from big-money donors. Frustration over that stance reportedly led to her finance director resigning in March. The senator raised $6 million from 135,000 donors in the first quarter. She officially launched her campaign in February after forming an exploratory committee at the end of 2018.
Since then, Warren has risen in the polls on the back of a series of detailed policy proposals and a well-received performance in the first debate. She currently polls at 13.8% among Democrats nationally, according to the Real Clear Politics polling average, compared with less than 7% at the end of March.
The former professor has built a reputation as a policy leader in the field of candidates, releasing detailed proposals to reform corporate taxes, provide student loan forgiveness and revamp the State Department, among other issues. She has also called for President Donald Trump to be impeached and to abolish the Electoral College.
Warren is one of the architects of the Consumer Finance Protection Bureau. She is one of a few candidates who supports banning private health insurance as part of moving toward "Medicare for All."
The deadline for candidates to file their second-quarter fundraising reports with the Federal Election Commission is July 15.
