Democratic nominee Kamala Harris hammered former President Donald Trump’s manufacturing record ahead of his visit to the battleground state of Michigan on Friday, pointing out that offshoring of U.S. jobs increased during the Republican nominee’s first White House term despite his grand promises to revitalize the nation’s industrial base.

“Donald Trump is one of the biggest losers of manufacturing in American history,” Harris, who outlined her own domestic manufacturing priorities earlier this week, said in a statement Thursday. “He makes empty promise after empty promise to American workers, but never delivers. As president, he cut taxes for corporations, encouraged outsourcing, and lost nearly 200,000 manufacturing jobs, including auto jobs. He has joked about firing workers, supported state anti-union laws, and suggested companies move jobs out of Michigan.”

“Yet it was Trump’s trade deal that made it far too easy for a major auto company like Stellantis to break their word to workers by outsourcing American jobs,” Harris continued, pointing to the United States-Mexico-Canada Agreement (USMCA). “As one of only 10 senators to vote against USMCA, I knew it was not sufficient to protect our country and its workers. Many who voted for this deal conditioned their support on a review process, which as president I will use.”

“On his watch, a Warren car plant closed and the auto industry bled thousands of jobs.”

Trump has two campaign events scheduled in Michigan on Friday as recent polling shows him narrowly behind Harris in the key state, which President Joe Biden won in 2020.

Despite his starkly anti-worker record, Trump has sought to appeal to members of the United Auto Workers (UAW)—which has endorsed Harris—and other unions in Michigan and elsewhere during his bid for another term, issuing sweeping promises and dire warnings about the future of U.S. manufacturing if he loses in November.

If he doesn’t prevail, Trump said during a town hall in Flint, Michigan last week, “there will be zero car jobs, manufacturing jobs.”

“It will all be out of here,” he added.

Democrats have countered such claims by pointing to the fact that offshoring accelerated under Trump, particularly due to the passage of the Tax Cuts and Jobs Act—a law that delivered massive tax breaks to the rich and incentivized corporate offshoring.

A Public Citizen analysis published in the final months of Trump’s presidency found that the Republican nominee’s administration “awarded more than $425 billion in federal contracts to corporations listed among those responsible for offshoring 200,000 American jobs” during his first term.

The Economic Policy Institute separately found that roughly 1,800 U.S. factories shuttered during Trump’s first term.

One of those factories was a General Motors plant in Warren, Michigan—a closure that the Democratic National Committee (DNC) highlighted with a billboard display in the city ahead of Trump’s visit Friday.

“Donald Trump broke his promises to Michigan’s working families,” said Stephanie Justice, a DNC spokesperson. “On his watch, a Warren car plant closed and the auto industry bled thousands of jobs.”

In a video released earlier this week as part of its 2024 election efforts, UAW president Shawn Fain called Trump a “con man” who is merely posturing as an ally of the working class while pushing policy changes that would primarily benefit those of his own class, the ultra-wealthy.

“We can’t get fooled or distracted by a con man like Donald Trump. That’s why I’m voting for Kamala Harris,” said Fain. “That’s why our union has endorsed Kamala Harris, and that’s why our country needs Kamala Harris as our next president.”

Throughout the 2024 campaign, Trump has proposed aggressive tariffs to help protect and restore U.S. manufacturing. Earlier this week, the former president singled out John Deere, a federal contractor that has announced plans to lay off roughly 2,000 workers and shift some of its production to Mexico.

“I am just notifying John Deere right now that if you do that, we are putting a 200% tariff on everything that you want to sell into the United States,” Trump said during a campaign event in Pennsylvania earlier this week.

In an op-ed for Common Dreams on Thursday, Labor Institute executive director Les Leopold implored the Harris campaign and the Democratic Party more broadly to do more to counter Trump’s messaging, specifically by calling out and moving to penalize companies that carry out mass layoffs while rewarding their rich investors with stock buybacks and dividends.

“Because Trump has difficulty focusing on a coherent message, the field is still open for the Democrats to put forth a new policy that directly affects the jobs of millions of workers,” wrote Leopold. “Harris should give a primetime talk and focus on the $700 billion in taxpayer money that now goes to private corporations for goods, services, and subsidies.”

“Here’s the line she should stress: No taxpayer money shall go to corporations that lay off taxpayers or conduct stock buybacks,” he continued. “The Democrats must decide, and soon, whether they really are the party of the working class. If they are, then they must fight hard to save worker jobs from unabated corporate greed.”
