The Chicago native and confirmed Sox fan formerly known as Robert Prevost couldn’t help but get caught up in a White Sox chant earlier this week as he rode through Vatican City in the popemobile, video shows.

As the Popemobile approached the White Sox admirers, Pope Leo XIV — who hails from the Windy City — could be seen mouthing, “White Sox,” as captured in a video shared by TikTok user jacobusch.clan. This show of support comes days after Pope Leo XIV rocked a White Sox cap while greeting other visitors, including a bride and groom.

Thousands went to the first American pope’s old haunt on the South Side to hear a message from the man they once knew as Robert Francis Prevost.
