Biden has struggled in recent weeks to be heard from his makeshift home TV studio over the noise of duelling national crises. But after another night of violent protests, he ventured out into public for just the third time since the pandemic arrived in mid-March.
His hopeful and collaborative approach marked a sharp contrast to that of President Donald Trump, who has made little effort to unify the country. The Republican President slammed governors as "weak" during a video teleconference on Monday and demanded tougher crackdowns on protesters. Trump also lashed out at Biden on Twitter, writing that "Sleepy Joe Biden's people are so Radical Left that they are working to get the Anarchists out of jail, and probably more".
Biden's softer approach may foreshadow how he presents himself in the five months before the presidential election, emphasising calm and competence as a contrast to a mercurial president. It is an approach that carries the risk of being drowned out by Trump's much louder voice.
"He's not in office, and he certainly does not have the megaphone like the person currently occupying the White House does, but I do think our people are looking for someone who can make them feel better during these extremely tough times," said Rep. Val Demings of Florida, whom Biden is considering as a running mate. "America just needs to be reassured that there's someone who's understanding, someone who's willing to say, 'Yes, we do have some issues,' and someone who's willing to address it."
Biden delivered a well-received address on Friday calling on white people to shoulder the responsibility of ending America's systemic racism. But he was largely out of sight over the weekend, which marked the fifth anniversary of the death of his son Beau Biden from brain cancer.
Biden and his wife, Jill, marked Memorial Day by laying a wreath at a veterans' memorial near his Wilmington home last week, and the former vice-president's campaign posted pictures of him visiting a protest site in the city on Sunday afternoon. Earlier, he wrote a post on Medium expressing empathy for those despairing about the police killing of George Floyd.
In the early moments of Monday's gathering at the Bethel AME church in Wilmington, Biden listened quietly and took notes in a spiral notebook. All the attendees, including Biden, wore face masks but lowered them as they spoke.
"The vice-president came to hear from us. This is a homeboy," pastor Sylvester Beaman said before everyone bowed their heads in prayer.
Biden's standing with the black community weighs heavily as he works to deny Trump a second term. African Americans rescued Biden's flailing primary campaign, but it's unclear if they will turn out for him in large numbers in November.
"I want to make something clear. I don't expect anything from the black community," Biden said Monday, insisting he has never taken their support for granted. The former vice-president has been doing cleanup since telling a prominent black radio host a week and a half ago that African Americans who back Trump "ain't black".
Yet the mayors who spoke with Biden, three of whom are black, were clearly frustrated and angry with Trump, who has offered military support to address violent protests while denying them federal support to address the coronavirus fallout and repeatedly attacking them on social media.
"To see the President of the United States say that he's going to send the military into our communities but hadn't mentioned sending a single dime of support into our communities, speaks to where we are in America," said Atlanta Mayor Keisha Lance Bottoms.
Much of Biden's campaign strategy centres on trying to draw a contrast with Trump on temperament and values. He has called the White House contest a battle for the soul of the nation and has been particularly forceful in condemning Trump's handling of moments of racial tension.
In an election that is likely to be a referendum on the sitting President, some Biden aides say privately that the best plan may be to let Trump do himself in.
Yet there is also a recognition that Biden needs to do more than simply wait for voters who may be turned off by Trump to turn toward him. Some Democrats who have criticised Biden for not being more visible during the onset of the coronavirus said he is making the right moves now.
"I'm sure they have some reluctance, understandably, right now to politicise it. That's not who he is," said Democratic strategist James Carville. "There might be a time for eloquence, but I think that simplicity is eloquence right now."
