WATCH: Harris speaks with union members at Labor Day campaign event in Detroit

Vice President Kamala Harris began marking Labor Day with a rally at a high school gymnasium in Detroit, where hundreds of audience members wore bright yellow union shirts and hoisted “Union strong” signs. She noted that one of the nation’s first Labor Day parades happened in Detroit around 140 years ago and that “every person in our nation has benefited” from unions’ work.

“Everywhere I go I tell people, ‘Look, you may not be a union member, you’d better thank a union member,'” Harris said, noting that collective bargaining by organized labor helped secure the five-day work week, sick-pay and other key benefits and solidify safer working conditions.

“When unions are strong, America is strong,” she said.

Harris later was set to attend Pittsburgh’s Labor Day parade, marking the first time she and Biden will both speak at a campaign event since the surprising election shakeup that provided a fresh jolt of Democratic enthusiasm to the 2024 election.
