A worker group in North Carolina on Wednesday criticized former U.S. President Donald Trump and one of the Republican nominee’s allies for campaign stunts involving garbage trucks.

After struggling to open the truck’s door—which led to a viral video clip and concerns about Trump’s physical condition—the ex-president climbed into the passenger seat of a white truck adorned with American flags and a banner that said, “Trump, Make America Great Again! 2024.”

Wearing an orange high-visibility vest that he also wore during a later rally in Green Bay, Wisconsin, Trump took aim at President Joe Biden and Vice President Kamala Harris, the Democratic nominee, saying to reporters: “How do you like my garbage truck? This truck is in honor of Kamala and Joe Biden.”

In a pair of social media posts, the Durham Workers Assembly highlighted that the dump truck gimmick followed Trump donning an apron last week at a McDonald’s in another swing state—Pennsylvania—where he worked a french fry fryer and dodged questions about raising the minimum wage.

“First slinging fries at McD’s now this!” said the Durham, North Carolina branch of the Southern Workers Assembly, which aims to organize the unorganized working class in the U.S. South and coordinate actions across the region.

“A billionaire sleazeball acting like he is a worker is beyond gross, and slap in the face to all working-class people,” the group declared on social media. “Workers must organize and raise up to smash MAGA fascism!”

The Durham Workers Assembly noted that “pro-Trump fellow billionaire” Vivek Ramaswamy participated in a similar stunt, arriving at a Wednesday campaign event in Charlotte, North Carolina on the back of a sanitation truck.

The garbage truck events, as Politicoexplained, came in response to “Biden responding to a comedian at the former president’s Sunday rally at Madison Square Garden calling Puerto Rico a ‘floating island of garbage.’ Biden, addressing the racist joke on Tuesday, appeared to call Trump’s supporters ‘garbage’ in return, which Republicans seized on even as the White House said he was referring to Trump’s ‘supporter’s’— note the apostrophe placement—’demonization of Latinos.'”

Winning over working-class voters has been a priority for both campaigns. Many national unions have endorsed Harris—though, notably, not the International Brotherhood of Teamsters, whose leader spoke at this year’s Republican National Convention and faced criticism for not backing a presidential candidate for the first time in decades.

The United Auto Workers is among the unions that have endorsed Harris. In a Tuesday speech, UAW president Shawn Fain advocated for working-class unity against Trump, whom he’s called a “scab,” and emphasized that “we engage in politics as a union because it is core to our fight for economic and social justice.”

Unions and worker advocates cheered Harris’ selection of Minnesota Gov. Tim Walz as her running mate. A former public school teacher, Walz has slammed Trump and his vice presidential candidate, Sen. JD Vance (R-Ohio), as enemies of the working class, saying that “the only thing those two guys know about working people is how to work to take advantage of them.”

Vance is a former venture capitalist known for his memoir Hillbilly Elegy, which was made into a movie. As Rolling Stone’s Tim Dickinson wrote in September: “In the pages of his book, Vance presents a dim view of the actual poor, whom he refers to as ‘welfare queens’ and accuses of ‘gaming’ America’s too-generous social services. And as he campaigns in 2024, Vance is wielding his book as both a shield and a cudgel, using the tale of his hardscrabble youth to distract from the fact that he’s now a multimillionaire member of the Senate, while simultaneously lashing out at the ‘elites’ for looking on his kind with contempt.”

During a Thursday campaign event, Walz acknowledged the garbage truck stunt while lambasting Trump’s tariff plans.

“This dude’s nearly 80 years old. He damn near killed himself getting in a garbage truck. You would think over 80 years you would understand how a tariff works,” Walz said. “Smarter people than Donald Trump—which is a good chunk of folks—CEOs of companies like Black & Decker, AutoZone, and Columbia, have gone on the record to say, if Donald Trump goes forward with this plan, they will simply have to raise prices and pass it on to you.”
