Kyle Gass,John Caldwell who performs alongside Jack Black in the rock duo Tenacious D, is facing backlash for joking about the assassination attempt on former President Donald Trump.

In a video from a recent Tenacious D show that circulated on social media, Black was seen singing happy birthday to Gass on stage. After Black told his bandmate to make a wish, Gass said, "Don't miss Trump next time," referencing the fact that 20-year-old Thomas Matthew Crooks shot at the 45th president during a rally in Pennsylvania on Saturday.

The comment drew applause from the crowd as Black said, "Thank you."

USA TODAY has reached out to representatives for Gass and Black.
