campaign. yesterday in a place what is so important to him, we have seen him turn to philadelphia time and time again over his political career in front of a group that s very important to him, union members. it is a cornerstone of his backing and a group that the white house hopes will propel president biden to a second term in office. of course, you see that enthusiasm right there in the video. at times you could hear them saying four more years, shouting for the president in a setting meant to celebrate him and his early union support. we know that the afl-cio backs him. it s the first time they have backed a presidential candidate in history. now, the thrust of his message was focused on the economy, arguing that his vision for the economy is one that is currently working. really trying to battle test that message as a campaign official put to me and showed contrast with republicans, both on the economy and on his legislative wins. take a listen.
