Footage of former President Donald Trump listening to a “Let’s Go Brandon” chant at the LIV Golf tournament went viral Sunday.

The former president was flanked by his son, Donald Trump Jr., Fox News host and Daily Caller co-founder Tucker Carlson, as well as Republican Georgia Rep. Marjorie Taylor Greene, all of whom were smiling and laughing as the chant broke out over the course, video shared on Twitter shows. Trump Jr.’s girlfriend, Kimberly Guilfoyle, and Eric Trump were also in attendance.

Trump was wearing his iconic “Make America Great Again” hat, embroidered with the number “45” on the side, as he pumped his fist to the beat of the chant. The chant was first made popular after an interviewer misheard a crowd of NASCAR fans yelling “Fuck Joe Biden,” claiming they were actually cheering “Let’s Go Brandon,” for driver Brandon Brown.
