After the United Auto Workers union formally endorsed President Joe Biden last week, former President Donald Trump criticized the union chief on Sunday, prompting a response from the Biden campaign — as the two campaigns compete for the support of union voters, who have been influential in some past elections.
The heated debate over the Michigan-based UAW’s endorsement comes as the 2024 Biden-Trump team says they are keen for a rematch in November.
In a statement Sunday evening, the Biden-Harris campaign criticized what it called Trump’s “wounded ego” after the former president attacked UAW president Sean Fine on social media.
“So … clearly losing the UAW endorsement to Joe Biden has left Donald Trump’s wounded ego with SCAB,” Communications Director Michael Tyler said.
The statement came after Trump called Vine a “STIFF” in a lengthy social media post in which he also accused the union leader of “selling out” the US auto industry to China and criticized Biden’s support for electric vehicles.
Trump: “Sean Vine doesn’t understand this or has no idea about it.” books. “Get rid of this drug & Vote for DJT. “I will bring the car industry back to our country.”
Earlier in the day, Fein praised Biden’s support for unions at a press conference interview with CBS’ “Face the Nation” and said he “can’t understand any union supporting Trump.”
“When you look at these two candidates, you know, Joe Biden has a history of serving others and serving the working class and fighting for the working class, and standing up for the working class. Donald Trump has a history of serving himself and standing up for the people.” “Billionaire class. This goes against everything the working class stands for,” Fine said, hours before Trump posted.
Biden, who earned the UAW’s endorsement in 2020 as well, has repeatedly described himself as the “most pro-union” president in history, and last September became the first modern president to join a picket line, with auto workers in Detroit.
Trump attacked Biden’s union record, calling it “bullshit.”
Exit polls from the 2016 election showed former Secretary of State Hillary Clinton stumbling with unionized workers in Ohio and Michigan. Trump beat her on both.
In 2020, Biden narrowly won Michigan and two other Rust Belt states, Pennsylvania and Wisconsin, which Trump had won four years earlier.
Fine made the UAW’s official endorsement for 2024 last week at a convention in Washington, D.C., where he also attacked Trump in a strongly worded speech.
“Donald Trump is just scabs,” he said on Wednesday. “Donald Trump is a billionaire, and that’s what he stands for. If Donald Trump worked in an auto plant, he wouldn’t be a member of the UAW — he would be a company man trying to squeeze the American worker.”
