Sen. Elizabeth Warren's campaign said on Saturday it raised $14 million in the 10 days after the New Hampshire Democratic primary.

The big picture: Warren "entered February with among the least money in the bank, only $2.3 million, of any candidate" the New York Times reported two days ago.

Center-left think tank Third Way urgently called on the Democratic front-runners of the 2020 presidential election to challenge Sen. Bernie Sanders on the South Carolina debate stage on Feb. 25, in a memo provided to Axios' Mike Allen on Saturday.

What they're saying: "At the Las Vegas debate ... you declined to really challenge Senator Sanders. If you repeat this strategy at the South Carolina debate this week, you could hand the nomination to Sanders, likely dooming the Democratic Party — and the nation — to Trump and sweeping down-ballot Republican victories in November."

Twitter has reportedly suspended about 70 accounts posting pro-Bloomberg content, the Los Angeles Times reports.

The big picture: The presidential campaign is paying Instagram, Facebook and Twitter users in California to post messages of support on their personal accounts, the Wall Street Journal reported this week. That effort could "later be deployed nationwide," per WSJ.

Election volunteers in charge of tallying results in Saturday's Democratic caucus are being asked to sign legal agreements to keep them from hurting the reputation of the Nevada Democratic Party, the Washington Post reports.

Why it matters: These nondisparagement agreements come after Democrats used an app created by Shadow Inc. that threw Iowa's caucuses into disarray, leading to delayed results amid evidence of an error-riddled process.

Sen. Bernie Sanders told reporters at a campaign stop Friday that he was briefed by U.S. officials "about a month ago" on Russia's attempts to assist his 2020 presidential campaign, AP reports. "It was not clear what role they were going to play," he added.

Driving the news: Sanders' comments followed a Washington Post report that U.S. officials briefed Sanders on Russian efforts to help his 2020 campaign "as part of an effort to interfere with the Democratic contest."

Mike Bloomberg said Friday his company will release women identified to have signed three nondisclosure agreements so they can publicly discuss their allegations against him if they wish.

Why it matters, via Axios' Margaret Talev: Bloomberg’s shift in policy toward NDAs comes as he tries to stanch his loss of female support after the Las Vegas debate. It is an effort to separate the total number of harassment and culture complaints at the large company from those directed at him personally. That could reframe the criticism against him, but also protect the company from legal fallout if all past NDAs were placed in jeopardy.

Former New York City Mayor Michael Bloomberg has dropped in favorability days after drawing boos at his debut debate performance as a Democratic presidential candidate, according to new Morning Consult polling.

By the numbers: 17% of Democratic primary voters list Bloomberg as their top choice if a primary or caucus were held in their state — down from 20% before the Las Vegas debate. His net favorability has fallen 20 points from Morning Consult's pre-debate poll, when 25% of Democratic primary voters found him unfavorable. Now, 35% find him unfavorable.

In the last two months, Bernie Sanders has surged 20 points among college students to become the group's clear 2020 favorite, according to a new College Reaction/Axios poll.

Why it matters: The numbers reflect the extent to which young Democratic voters are embracing socialism and rejecting moderate choices.

Mike Bloomberg's campaign said Friday that vandalism at its Knoxville, Tenn., office "echoes language from [Bernie Sanders'] campaign and its supporters," even as it admitted that it didn't know who was responsible.

Why it matters: It marks a massive escalation in the war of words between the two Democratic presidential candidates that has spilled into the open over the last week — covering everything from their heart health to debate performances to electability.
