LOS ANGELES (AP) — The trauma Migos rapper Quavo suffered after witnessing his nephew Takeoff being gunned down last year is a disturbing sight he doesn’t want anyone else to experience.

Through his pain, Quavo found his purpose as a vocal advocate against gun violence. He met privately with some powerful political figures including Vice President Kamala Harris then later spoke on a panel about combating the issue during the Congressional Black Caucus legislative conference in Washington on Wednesday.

The Grammy-nominated rapper said Takeoff’s untimely death in 2022 ultimately convinced him to speak up.

“I feel like your calling comes at the least expected times,” said Quavo, who also honored his nephew with their Migos bandmate Offset during the BET Awards earlier this summer.

Police say Takeoff was an innocent bystander who was shot outside a Houston bowling alley after a disagreement over a lucrative dice game led to gunfire. Takeoff’s death was the latest in a string of fatal shootings in recent years that involved hip-hop stars such as Nipsey Hussle, Pop Smoke, PnB Rock and Young Dolph.

“You don’t think nothing is going to happen,” Quavo continued. “I need to step up to the plate and hit a homerun. I have to do something about it, so it won’t happen to the masses — especially in our culture. I don’t want this to happen to the next person. I want to knock down these percentages.”

Quavo joined a panel discussion Wednesday alongside Democratic Sen. Raphael Warnock, Republican Lucy McBath — whose activism was propelled after the shooting death of her teenage son — and Greg Jackson of the Community Justice Action Fund. It was a solutions-oriented conversation on community intervention strategies, the battle with gun violence and the power in advocacy.

Earlier, Quavo arrived at the conference hand-in-hand with his sister Titania Davenport, the mother of Takeoff.

After Quavo met with Harris, the vice president praised the rapper and Davenport’s “call for action” to prevent gun violence.

“We need to do better with the control of guns,” Quavo said. “We need to figure out how do we keep these types of incidents from happening to people going anywhere and thinking they can hurt somebody where it shouldn’t happen.”

After Takeoff’s shooting, Quavo often asked himself “How do we use (guns) safely?”

“And how do you keep them out of the hands of people that make bad decisions?” he said. “I’m kind of in a half-and-half place. Even police have guns. Unfortunately, some of the people in our culture and loved ones have been lost to police brutality. It’s all about choices and how we can put a filter on who can use these guns.”

Jackson said Quavo’s voice could make a difference. He applauded the rapper for sitting down with members of Congress, offering his firsthand insights and putting the pressure on them for impactful change.

“His voice and commitment around community violence intervention could provide more resources for those who are most at risk,” said Jackson, whose Community Justice organisation hosted Quavo for a day of advocacy. They are both pushing for passing of the Break the Cycle of Violence Act, which would provide a $6.5 billion federal grant to communities to curb gun violence, create prevention programs, job training and workforce development for youths.
