The phrase began in October 2021 after a NASCAR interview at Talladega, when a crowd chant was reported on air as Lets go Brandon and quickly became code among Biden critics. On Christmas Eve 2021, during the NORAD Santa tracker call, Oregon caller Jared Schmeck ended his chat with the phrase and Biden repeated it back with I agree. Clips spread across news and social media that day, and the brief reply has stayed popular as a shareable reaction because it sounds like Biden endorsing his own criticism.
