A supporter of President Trump’s claimed he was viciously pummeled by Mike Ness – lead singer of the iconic punk band Social Distortion – during a concert in Northern California, according to reports on Wednesday.

Tim Hildebrand said he suffered two black eyes, a busted lip and concussion at the hands of Ness during a Social Distortion show at Ace of Spades concert hall in Sacramento on July 19, KOVR-TV reported.

Ness, 56, had been criticizing Trump on stage, and Hildebrand – a Republican – didn’t like it.

“I pretty much said I paid for your music, not your politics,” said the farmer from rural Galt, Calif., about 30 miles away from Sactown. “I stood pretty much with my silent protest with my middle finger up for the next two songs.”

Cellphone video of the incident appears to show Ness motioning for the man to come forward – before the singer spit on him.

Then Ness puts his guitar down and wades into the crowd and gets into a tussle that’s obscured from the camera’s view.

The crowd cheered on Ness with at least one fan screaming: “Whip his ass, Mike!”

Hildebrand described the melee: “(Ness) takes his guitar off, jumps off the stage and proceeds to punch me multiple times in the head.”

“I wasn’t able to defend myself because people in the crowd were holding me back,” said Hildebrand, claiming he was then thrown out of the venue by security.

He’s since reported the incident to Sacramento police.

Cops said they’re aware of the incident and are investigating while the band had no comment, KOVR reported.

“Someone that has the status that he does shouldn’t get away with assaulting someone,” Hildebrand said.
