By ABC News–

Sen. Kamala Harris has suspended her presidential bid, bringing to a close her historic effort to secure the Democratic nomination.

“I’ve taken stock and looked at this from every angle, and over the last few days have come to one of the hardest decisions of my life. My campaign for president simply doesn’t have the financial resources we need to continue,” she wrote in a letter to supporters. “I’m not a billionaire. I can’t fund my own campaign. And as the campaign has gone on, it’s become harder and harder to raise the money we need to compete. In good faith, I can’t tell you, my supporters and volunteers, that I have a path forward if I don’t believe I do. So, to you my supporters, it is with deep regret — but also with deep gratitude — that I am suspending my campaign today.”

A video is coming shortly from the campaign.

The announcement comes after her campaign drastically cut her staff in October, funneling most of her campaign’s resources toward working on a strong victory in Iowa and leaving other early voting states such as New Hampshire and South Carolina with minimal staffing and funding.

“I’m moving to Iowa,” the senator joked at rallies, as she vowed to campaign in the state each week.

Still she plateaued in the polls in the single digits.

Harris entered the race January 2019 speaking before a crowd of 20,000 people, one of the largest in the 2020 cycle. The senator’s presidential hopes were amplified by a sudden boost of support after a breakthrough moment during the first Democratic presidential debate. On the debate stage, Harris, who is black and Indian American, challenged former Vice President Joe Biden on his past stances on busing policies.

“There was a little girl in California who was part of the second class to integrate her public schools and she was bused to school every day. That little girl was me,” Harris said.

On Tuesday, Biden complimented Harris as a competitor.

“She is a first rate intellect, a first rate candidate and a real competitor,” he told reporters at an event in Iowa. “I have mixed emotions about it because she is really a solid, solid person and loaded with talent. I’m sure she’s not dropping out on wanting to make the changes she cares about.”

Those changes, Harris underscored on the trail and in her letter to supporters, centered on “fighting for people whose voices have not been heard or too often ignored.”

On the campaign trail, Harris’ record as district attorney of San Francisco and later attorney general of California, became a frequent area of criticism from her fellow presidential contenders.

As a presidential candidate, Harris’ team sought to highlight her efforts as a progressive prosecutor who championed criminal justice reform and held the powerful accountable. In stump speeches across the country, Harris made a pitch to voters about why she was best poised to “prosecute the case against four more years of Donald Trump.”

Harris’ popularity rose in part because of her harsh questioning of Trump cabinet nominees such as Supreme Court Justice Brett Kavanaugh. It was those same skills her team tried to highlight as the House impeachment inquiry into President Trump got underway.
