Tenacious D’s Kyle Gass is under fire after making a controversial comment about the attempted assassination of Donald Trump.

On July 14, just one day after Trump was hit by a bullet at a rally in Butler, Pa., Tenacious D — a rock duo comprised of Gass and actor Jack Black — played a show in Australia’s ICC Sydney Theatre where they simultaneously celebrated Gass’ 64th birthday.

In fan-captured footage, Black can be seen presenting a birthday cake to Gass on stage and asking him to “make a wish.” Gass responds, “Don’t miss Trump next time,” referencing the less-than-day-old shooting. The video also captures the audience responding with laughter.
