On the first Monday of September, Americans nationwide celebrate Labor Day, a public holiday honoring the country’s working population.

This federal holiday recognizes the vital contributions made by workers in every sector, commemorating the strength, resilience, and spirit of America’s workforce.

Speaking to the nation from the White House, president Joe Biden said, “Workers are the backbone of this nation, the engine that powers our prosperity and our progress.” He hailed the efforts of America’s essential workers who have kept the country running during the COVID-19 pandemic and urged the nation to remember their sacrifices and contributions.

Meanwhile, Vice President Kamala Harris and President Joe Biden are co-headlining a campaign event Monday in the marquee battleground state of Pennsylvania as Harris balances presenting herself as a new way forward while remaining intensely loyal to Biden and the policies he has pushed.

The pair will attend Pittsburgh’s Labor Day parade and offer some remarks, the first time the two have shared a speaking slot on the political stage together since the surprising election shakeup that provided a fresh jolt of Democratic enthusiasm to the 2024 election.

Harris’ campaign has said Pennsylvania voters are newly energized since Harris moved to the top of the ticket six weeks ago, with tens of thousands of new volunteers signed up to canvass for her and Minnesota Gov. Tim Walz, the Democratic vice presidential nominee. Harris’ and Biden’s appearance at the parade, one of the largest such gatherings in the country, is part of a battleground state blitz with just over two months until Election Day.

Harris, 59, has sought to appeal to voters by positioning herself as a break from poisonous politics, rejecting the acerbic rhetoric of her Republican opponent, former President Donald Trump, while looking to move beyond the Biden era as well. Yet while her delivery may be very different from Biden’s, Harris’ agenda is chock-full of the same issues he has championed: capping the cost of prescription drugs, the Affordable Care Act, the economy and helping families afford child care.

We fight for a future where we build what I call an opportunity economy, so that every American has the opportunity to own a home, start a business and to build wealth and intergenerational wealth. And a future where we lower the cost of living for America,” she said at a recent rally, echoing Biden’s calls to grow the economy from the bottom out and the middle up.

Harris briefly appeared on stage with Biden after the president delivered his remarks on the opening night of last month’s Democratic National Convention, but the two haven’t shared a microphone at a political event since Biden himself was running for office. At that time, the campaign was using Harris mostly as its chief spokeswoman for abortion rights, an issue they believe can help them win in November as restrictions grow and health care worsens for women following the fall of Roe v. Wade.
