President Biden and Vice President Kamala Harris will come together for their first joint campaign event since Harris took over the lead on the ticket in July. Scheduled for Monday in Pittsburgh, they will honor the significance of labor unions, which play an essential role in mobilizing Democratic support. Biden has consistently branded himself as the most pro-union president in American history, notably becoming the first sitting president to participate in a picket line last year.

In this event, Harris is aiming to adopt the pro-worker identity that Biden has cultivated. She previously spearheaded a task force during her vice presidency to explore government interventions that could bolster union membership. However, some business figures perceive her as more accommodating to corporate interests and pliable in her policies compared to Biden.

At the Pittsburgh gathering, both leaders will be present at a local union hall with Pennsylvania’s Governor Josh Shapiro and Senator Bob Casey, who is running for re-election. The event is expected to draw significant attendance from leaders of major unions, including the International Brotherhood of Electrical Workers, the A.F.L.-C.I.O., and the United Steelworkers, further emphasizing the Democratic commitment to labor issues.
