The singer of a popular punk rock band criticized the former president and his supporters during a recent show.

Casey’s expletive-laden rant continued, “You’re being duped by a bunch of grifters and billionaires who don’t give a shit about you or your family. They care about their fucking tax breaks and the money they can put in their pocket. If you consider yourself a patriot and you’re spouting off that election-denying shit, I will fight your ass outside if you want to. Wake the fuck up!”
