Che and co-host Colin Jost mocked Trump after he experienced apparent technical difficulties at a campaign rally in Wisconsin and criticized the height of the microphone stands.

Trump then went up to the mic stand on his lectern and bobbed his head up and down, mouth open, in a move that many described as mimicking oral sex.

Jost reacted to a clip of Trump’s wild act.

“Dude. Even more embarrassing, the microphone immediately tapped him on the back of the head,” Jost quipped.
