FOX

Rudy Giuliani was revealed as a contestant, causing one judge to walk off set.

The disgraced politician and former right-hand man of Trump was revealed as The Jack in the Box on the FOX singing contest Wednesday night. Giuliani got the boot after his performance of Bad to The Bone.

While he is performing the song, you can see a clearly pissed off judge, Ken Jeong, say "I'm done" before walking off the set.

It was reported back in February that Ken and Robin Thicke walked off in disgust, but that didn't happen Wednesday.

Why did he do the show? Giuliani wants his granddaughter to know that she should try everything, even things that are completely unlike her.
