The two progressive senators have refrained from engaging each other in negative attacks throughout the Democratic primary.
On Monday, CNN reported that in a meeting between Sanders and Warren in late 2018, Sanders said to Warren that a woman could not win the presidency in a meeting at Warren's Washington apartment. "I thought a woman could win; he disagreed".
Two people Warren spoke to directly after the meeting and two people familiar with it told CNN that they both agreed to stay civil during the presidential campaign and talked about how to best defeat President Trump.
While some claimed to be requesting refunds, a number of Warren supporters using the hashtag said it had encouraged them to donate more money to her campaign. "In my view, a woman could be elected president of the United States", Sanders said.
Sanders told CNN in "an aggressive, on the record pushback" that the claims were absolutely false. "What I did say that night was that Donald Trump is a sexist, a racist and a liar who would weaponize whatever he could".
Warren, who released a statement Monday evening, said it was at a private meeting in December 2018 to discuss the 2020 election. "After all, Hillary Clinton beat Donald Trump by 3 million votes in 2016".More news: Rodgers-Adams connection on full display in Pack win
Others highlighted the fact that Ortham, though given an opportunity, declined to comment on behalf of the Warren campaign.
BBC North America reporter Anthony Zurcher said the rising tension has left some progressives concerned that both candidates could we weakened in the end.
"Direct denial from the accused source and a "no comment" from the camp it comes from. four anonymous sources, none of whom were in the room", commented journalist Jack Crosbie, formerly of Splinter News. Someone that every Democrat can believe in.
Trump may have inadvertently picked a fight with Sanders Sunday when the president highlighted the 78-year-old's strong poll performance and posted online: "So what does this all mean?" "One of the very important things that I hope that all the girls in this class understand is that you just as much as the boys have a right to become president", he told an elementary school class in 1987. In a fundraising email, her campaign asked supporters to respond if the "Bernie campaign's description rang false to you, too".
Warren has grown increasingly vocal over the past few months on the role of sexism and gender inequality in politics, including experiences the Massachusetts Democrat said she has endured in the years that she has been in public office.
With some critics focused their ire on Warren for not immediately pushing back against the reporting-which as of this writing her campaign has not done-other voices warned that there could be other forces at play.More news: Awesome Games Done Quick is overcome by raising 3.13 million for charity
"Over and over, we are told that women are not allowed to be angry".
Voters in Iowa go to the polls in three weeks, marking the first ballots cast in the 2020 presidential election. And Pete Buttigieg, a 37-year-old Midwestern former mayor who is openly gay and served in the military, represents dramatic change on paper but is more aligned with Biden on policy.
The escalation comes at a pivotal moment ahead of the Iowa caucuses and just before Tuesday's debate between the Democratic rivals, in Des Moines, where the candidates will nearly certainly be asked to clarify their different interpretations of the meeting.
Over the weekend, Politico reported that Sanders' campaign was instructing volunteers to tell voters wavering between the two progressive candidates that Warren's popularity was limited to "highly educated, more affluent people who are going to show up and vote Democratic no matter what" and that she was "bringing no new bases into the Democratic party".
