On Saturday, a tweet that contained a picture of an on-duty San Francisco firefighter wearing a "Let's Go Brandon" t-shirt began making rounds on Twitter — which has since prompted SFFD to take disciplinary actions against the City worker. The "Let's Go Brandon" chant — a rallying call that gained cultural prominence when a reporter interviewing the Sparks 300 race winner Brandon Brown at Talladega Superspeedway incorrectly described the chant in the background as "Let's Go Brandon" — has grown into a politically subversive slogan. The meme-able phrasing is now commonly synonymous with "F**k Joe Biden," though just a more family-friendly version of the profane sentiment. Recently, a San Francisco firefighter was photographed wearing a t-shirt with the slogan splayed across the top on the back.
