Biden on Friday said he would join the picket lines in Michigan on Tuesday.
Earlier Friday, UAW President Shawn Fain announced that workers at parts distribution centers at more than three dozen Stellantis and General Motors plants in 20 states will join the approximately 12,700 union members participating in the first strike at three plants.
Trump has recently sought to shore up support among union workers, especially in Rust Belt and battleground states like Pennsylvania, by pushing populist policies at a series of rallies. Biden, who bills himself as “the most union president in American history,” has meanwhile tried to quell union unrest over some government policies, including on energy and the environment.
Trump added that if the UAW leadership does not support him, “the autoworkers are toasting our great truckers to follow.”
Trump also made pointed comments about Biden’s handling of the migrant crisis, suggesting he would “go to the southern border instead and leave the auto industry alone!”
