President Biden became the first sitting U.S. president to join a picket line Tuesday as he expressed support for autoworkers in Wayne, Michigan, in their strike against the “Big Three” — Ford, GM and Stellantis.

President Joe Biden: “The fact of the matter is that you guys, UAW, you saved the automobile industry back in 2008 and before, made a lot of sacrifices. You gave up a lot. And the companies were in trouble. But now they’re doing incredibly well. And guess what: You should be doing incredibly well, too. It’s a simple proposition. It’s just about being fair. Folks, stick with it, because you deserve the significant raise you need and other benefits.”

President Biden was standing next to UAW President Shawn Fain. Donald Trump is speaking to autoworkers today at a nonunion auto plant near Detroit; he will be skipping tonight’s second Republican debate. Meanwhile, General Motors started hiring $14-an-hour scabs to cross the picket line.
