During the call, Biden made a few noteworthy statements. First, he promised to be the most pro-union president in history. “I’m going to be the strongest labor president you have ever had,” the former vice president said. “My uncle in Scranton, Uncle Ed, used to say, ‘Joey, you’re labor from belt buckle to shoe sole.' I’ve never been afraid to say the word ‘union.’ … You can be sure you’ll be hearing that word ‘union’ plenty of times if I’m in the White House. The words of a president matter.
