Harris gathered with Jacob Blake's father, two sisters and members of his legal team at a private airport in Milwaukee while Blake's mother and attorney Ben Crump joined by phone. Blake was not part of the conversation, according to a list of attendees released by the campaign. Joe Biden met with the family last week during a visit to Kenosha, the city where police shot Blake.

The meeting kicked off a packed day of Labor Day campaign events, with Harris scheduled to meet with IBEW union workers and Black business owners in Milwaukee, while Pence will tour an energy facility in La Crosse. Biden, meanwhile, is collecting a trio of endorsements from organized labour as he heads to Harrisburg, Pennsylvania, for an AFL-CIO virtual town hall with union President Richard Trumka. President Donald Trump planned an afternoon news conference from the White House.

Harris' morning meeting with Blake's family again underscored the two campaigns' differing approaches to addressing police shootings of Black men and women and the resulting protests, including some that have been violent. While Harris and Biden have met with Blake's family, Trump did not in a recent visit to Kenosha, instead meeting law enforcement officials and touring damage to businesses from the protests. Trump's narrow win in Wisconsin in 2016 helped to send him to the White House. The state's importance was underscored by all four candidates campaigning there over the past week.

The Biden campaign believes its labour support could help get out the vote in states like Wisconsin and Pennsylvania. According to details shared first with The Associated Press, the campaign will announce three union endorsements: the Laborers' International Union of North America, the International Union of Elevator Constructors and the National Federation of Federal Employees, collectively representing hundreds of thousands of union workers nationwide who can be mobilised to support the campaign.

Labour Day typically marks the unofficial start to the fall campaign season as candidates accelerate their activity for the final sprint to Election Day. But Monday's events are playing out this year against the backdrop of a pandemic that has upended campaigning, forcing much of the candidates' traditional activity online. Indeed, this marks Harris' first solo foray out on the campaign trail for in-person events since she was announced as Biden's running mate nearly a month ago. But Biden himself has stepped up his campaigning over the past week, travelling to Pittsburgh and Kenosha and holding two news conferences. Aides say to expect both Biden and Harris to increase their campaigning for the remaining weeks.

While the presidential campaign was roiled this past week by multiple reports recounting comments Trump allegedly made disparaging fallen soldiers, as well as the police shooting and violent protests in Kenosha, the focus on Labour Day is likely to return to the issue that polls consistently find at the top of voters' minds: the economy. A strong economy that was Trump's biggest asset for reelection has now become a potential liability, brought down by the coronavirus. The Biden campaign has emphasised the economic damage wrought by what Biden argues was an inadequate response to the pandemic that resulted in more loss of life and jobs than necessary. It's a line both Biden and Harris are likely to push while speaking to union voters.

The US economy has been steadily rebounding from its epic collapse in the spring as many businesses have reopened and rehired some laid-off employees. Yet the recovery is far from complete. Only about half the 22 million jobs that vanished in the pandemic have been recovered. Economic inequalities also appear to have widened, with lower-income and minority workers suffering disproportionately while affluent Americans have lost fewer jobs and even benefited from rising stock and home prices.
