John Mellencamp slams politicians for not doing more to prevent gun violence: 'They don't give a f*** about our children'

John Mellencamp is slamming lawmakers for not doing more to stop school shootings.

The "Small Town" singer criticized politicians over their response to gun violence, saying they "don't give a f*** about our children."

"Only, in America, can 21 people be murdered and a week later be buried and forgotten, with a flimsy little thumbnail, a vague notion of some sort of gun control law laying on the senators' desks," the 70-year-old musician and painter wrote on Twitter Tuesday, referring to the Uvalde, Texas, school shooting on May 24.

"What kind of people are we who claim that we care about pro-life?" he continued. Just so you know, anyone that's reading this... politicians don't give a f*** about you, they don't give a f*** about me, and they don't give a f*** about our children."

He concluded, "So, with that cheery thought in mind, have a happy summer, because it will be just a short time before it happens again."

Mellencamp's comments came on Tuesday as the Senate voted to advance a new bipartisan gun control bill. It would enhance background checks and give authorities up to 10 business days to review the juvenile and mental health records of gun purchasers under 21. Funding would also go to help states implement red flag laws as well as to expand mental health resources in communities and schools and boost school safety, among other things.

It would not include raising the minimum age to purchase an assault weapon from 18 to 21 or banning high-capacity magazines like the House of Representatives bills approved earlier this month.

The Uvalde shooter legally purchased an AR-15-style rifle on May 17 — one day after he turned 18. Three days later, he purchased a second rifle, and in between bought 375 rounds of ammunition. On May 24, he killed19 fourth graders and two teachers at Robb Elementary. The gunman also shot his grandmother in the face.

Mellencamp has long spoken out against gun violence, joining 200 other artists and music execs in 2016 in calling for gun reform in the wake of the Orlando nightclub shooting. Following the Uvalde shooting, he said on MSNBC's The Beat last week that news outlets should start showing the carnage of school shootings to open the eyes of those resisting reform.

"I don't know if you’re old enough, but I remember when Vietnam first started, and it was a conversation on the news," the father of five said. "But then, when they started showing dead teenagers, people did something about it, and the country united. I think that we need to start showing the carnage of these kids who have died in vain... If we don't show it, then they're dying in vain, because they're just going to pass more bulls*** laws like they're trying to get through now. Show us. Let the country see what a machine gun can do to a kid's head."
