Las Vegas (CNN) Sen. Elizabeth Warren indicated on Thursday that she would not disavow the help from a super PAC supporting her candidacy, a notable shift from a candidate who has spent most of the 2020 campaign railing against the influence of outside groups and criticizing her Democratic rivals for relying on super PACs.

"So look, the first day I got into this race over a year ago, I said I hope every presidential candidate comes in will agree, no super PACs for any of us," Warren told reporters on Thursday. "I renewed that call dozens of times and I couldn't get a single Democrat to go along with it."

"Finally, we reached the point a few weeks ago, where all of the men who were still in this race and on the debate stage, all had either super PACs or they were multi billionaires, and could just, you know, rummage around in their sock drawers and find enough money to be able to fund a campaign. And the only people who didn't have them were the two women. And at that point, there are some women saying, you know, that's just not right," she added.

She was referring to a group of progressive women who formed Persist PAC and will spend over $1 million to air a biography-focused television ad that links Warren to former President Barack Obama and claims Warren can "take on" President Donald Trump and "win."
