Rep. Jeff Duncan (R-SC) wore a “Let’s Go Brandon” mask on the House floor Monday.

“Let’s Go Brandon” has become a viral anti-President Joe Biden saying following a recent NASCAR race, where an NBC reporter claimed fans were cheering on the race winner, Brandon Brown, when they were actually chanting “F*** Joe Biden.”

“Spotted at House votes: GOP Rep. Jeff Duncan of SC wearing a mask with a phrase that Republicans are using in place of F*** Joe Biden,” tweeted POLITICO reporter Olivia Beavers.

In South Carolina, Oconee Democratic Party chairwoman Jody Gaulin was fuming mad at Duncan.

According to Newsweek, Gaulin told The Seneca Journal, “Not only does Jeff Duncan not deliver for the people of the third district—I cannot think of a thing he has truly done—he now sports a vulgar slogan on his mask and walks off the floor!”

“The hypocrisy of the Faith and Freedom BBQ is exposed!” the Democrat raged.
