Jack Black‘s Tenacious D bandmate Kyle Gass had one wish for his birthday — and it’s being called a disgusting sentiment after someone tried killing Donald Trump.

Gass was performing alongside JB in Sydney, Australia over the weekend — and when Jack asked him what his birthday wish was onstage … KG said, “Don’t miss Trump next time” — a clear reference to Thomas Matthew Crooks firing a shot at DT over the weekend.

You can hear the crowd mostly laughing and cheering in support of his 64th bday wish … but some people do seem to express shock as well, with one guy audibly saying “woah.”

It wasn’t long before Kyle’s comment reached a different crowd online — and they made it clear they didn’t share his POV … in fact, plenty of people are downright pissed about this.

As you can imagine … tons of folks are condemning this — saying it’s a green light for further violence, and we’ve learned Jack himself feels the same way. Sources with direct knowledge tell TMZ … Jack wasn’t aware Kyle would say this, and that he doesn’t condone violence.

Safe to say … he doesn’t share the same POV as Kyle — although it’s unclear if they talked about the remark after the fact. And remember … Jack’s a Biden supporter — he recently went and got onstage at a pro-Biden event … and made it clear he’d be voting for him.

Trump’s gotten a wave of support from other celebs after the assassination attempt. From Elon Musk to Amber Rose to Larsa Pippen, they’re all showing they’re team MAGA more than ever … but clearly, some stars are still very anti-MAGA despite what went down.
