Former Vice President Joe Biden's campaign has been facing pressure from Democratic operatives and activists, worried that his Latino outreach efforts are not enough and potentially a serious liability in the fall election.

Some say that his campaign, which is staffing up to improve those efforts, could learn lessons from the success of one of his former rivals.

Former President Barack Obama delivered a virtual commencement address on Saturday, urging the tens of thousands of graduates from historically black colleges and universities to "seize the initiative" amid what he described as a lack of leadership from leaders in the United States to the coronavirus pandemic.

Four years ago, Joe Biden took the stage at the Democratic National Convention in Philadelphia to the Rocky theme, looking out over a crowd of delegates waving red and white signs that bore his name. He encouraged fellow Democrats to unite and rally around Hillary Clinton.

Now, as Democrats plan to hold the convention that will nominate Biden, the chances that he'll bask in the same kind of scene this year seem ever more distant, as the Democratic Party faces the possibility of a limited in-person presence or virtual gathering.

Former New York Mayor Mike Bloomberg's presidential campaign will now pay health care costs for former staffers through November, after originally offering laid off workers coverage only through the end of April, according to an email from the campaign's human resources.

More than a quarter of the country's 18- to 29-year-olds say that their lives are worse because of President Trump, according to a new poll, the latest to show the motivating impact the president could have on the youngest subset of voters this election year.

The poll, by Harvard's Institute of Politics, found that 29% of that cohort say their lives are worse under President Trump's leadership, 39% say their lives are no different, and 15% say their lives are better.

If China was responsible for the coronavirus outbreak, the country should face consequences, President Trump said at Saturday's White House briefing.

"If it was a mistake, a mistake is a mistake," Trump said in response to a reporter's question. "But if they were knowingly responsible, yeah, I mean, then sure there should be consequences."

Trump has offered no evidence that the Chinese were responsible for the pandemic, but did say that a U.S. investigation into the outbreak is ongoing.

On a recent Saturday night, tens of thousands of people joined a nine-hour virtual dance party on Instagram Live that was hosted by DJ D-Nice. Some familiar big names have been dropping into what he calls "Club Quarantine," like John Legend, Joe Biden and Mark Zuckerberg.

But it was the appearance of former first lady Michelle Obama that seemed to have a big impact.

"Oh my gosh. Michelle Obama's in here," D-Nice exclaimed as Obama's appearance brought the music to a brief stop. "Yo, I swear, I don't even know who to play right now. My mind's completely blown."

Former President Barack Obama officially endorsed his former vice president, Joe Biden, on Tuesday, marking the Democratic establishment's formal consolidation around the party's presumptive presidential nominee.

U.S. Surgeon General Jerome Adams again acknowledged in personal terms the increased risk for African Americans from the coronavirus, which appears to be infecting and killing black Americans at a disproportionately higher rate.

When Amol Jethwani interviewed for a job on Mike Bloomberg's presidential campaign in December, the benefits were unlike anything he had heard of for political campaign field workers.

"They offered an incredible benefits package, which is unheard of for field staff, offering $8,000 a month for a regional role in addition to health care, technology, laptops, cellphones," said Jethwani.

Former campaign workers for Mike Bloomberg's presidential campaign have filed two separate proposed class-action lawsuits, alleging that the thousands of staffers laid off this month had been promised to be paid through the general election in November.

One lawsuit, filed by Donna Wood, a former field organizer for Bloomberg's campaign in Florida, alleges that the campaign misled employees, recruiting them to work for Bloomberg under false pretenses and had failed to pay the necessary overtime. The lawsuit was filed in federal court in New York City.

Brianna Wu is hoping for an upset.

The software engineer is looking to challenge incumbent Rep. Stephen Lynch (D-Mass.) for a second time. But, before that, she has to get on the ballot for September's primary.

For congressional candidates like Wu, that means collecting 2,000 signatures, no large number. But with in-person contact several limited by the coronavirus outbreak, even that feels impossible now.

The revolution that Bernie Sanders is promising depends on a new wave of young voters showing up at the polls to propel his campaign. But this week, the Vermont senator acknowledged that those voters, on which his success to some degree hinges, have not shown up in the way he'd hoped.

After 14 states held primary contests on Super Tuesday, Sanders acknowledged to reporters that he'd been "disappointed" with the results.

Former Vice President Joe Biden went on a romp across the South on Tuesday, winning over several states with large majorities of African Americans. Vermont Sen. Bernie Sanders won the largest state on the Super Tuesday map, California, where Latinos make up about a third of the Democratic electorate.

All told, the 14 states that voted Tuesday offer the clearest distillation yet of the two distinct paths that Sanders and Biden would take to build a winning Democratic coalition to defeat President Trump in November.

Tom Steyer, the billionaire hedge fund investor and environmental activist who staked his campaign on a strong finish in South Carolina, suspended his presidential campaign on Saturday.

Steyer aggressively courted the black vote in the state, with a focus on racial and economic justice but had a disappointing finish. Former Vice President Joe Biden was projected to win the state.

As Tuesday's Democratic presidential primary debate came to a close, each of the candidates was asked to name the biggest misconception voters have about them.

A day later, the question was still on the mind of Tom Steyer, the billionaire hedge fund investor who has barnstormed South Carolina, aggressively courting the black vote with a focus on racial justice and climate issues.

Former New York City Mayor Michael Bloomberg has now spent some $452 million on advertising since entering the Democratic presidential race in late November, according to the ad-tracking firm Advertising Analytics.

The multibillionaire, who is self-funding his campaign, has already spent more than $401 million on television and radio ads alone. That surpasses the $338.3 million that President Barack Obama's campaign spent on those ads during his entire 2012 campaign, according to Advertising Analytics.
