Run The Jewels rapper Killer Mike has spoken out against anti-gun activists following the March For Our Lives rally in Washington.
In an interview with the National Rifle Association he accused those wanting to change gun laws of being "the lackey" (obeying someone else's orders).
His comments have caused a backlash on social media, with people criticising his decision to speak to the NRA.
He's defended himself on Twitter.
Celebrities including Miley Cyrus, Jennifer Hudson and Ariana Grande have shown their support for anti-gun activists in America.
They all delivered passionate performances at the March For Our Lives rally in Washington, which took place after 17 people were killed in the Marjory Stoneman Douglas High School shooting in Florida last month.
Since then, students have been leading a political movement to tighten gun controls and end school shootings in America.
Support for gun control is highest among 18 to 29-year-olds, a study by the Pew Research Centre says. There was a spike after the Orlando nightclub shooting in 2016.
But Run The Jewels rapper Killer Mike has different views.
In a video posted by NRATV he describes himself as "very pro-second amendment" (the right to own guns written in the US Constitution).
There are nearly as many guns as people in the USA - around 90 for every 100 people.
During the interview, Killer Mike criticises those who think they are "woke" to the cause for tighter gun control in America, saying: "You're a lackey of the progressive movement, because you've never disagreed with the people who tell you what to do."
"I told my kids on the school walkout, I love you, if you walkout that school, walkout my house…we are not a family that jumps on every single thing an ally of ours does because some stuff we just don’t agree with.” -@KillerMike #MarchForOurLives pic.twitter.com/Gx8JLntmZ8— NRATV (@NRATV) March 24, 2018
He also says he actively discouraged his children from taking part in the national student walkouts against gun violence.
"I told my kids on the school walkout, I love you, (but) if you walk out that school, walk out my house," he said.
Wow, well this is massively disappointing. No more Run The Jewels obsession for me. https://t.co/2TuMcZc4CB— Adrienne_Tweets (@adriennetweets) March 24, 2018
"In Wakanda, everyone had guns." - Killer Mike, bumming me out right now.— Brian Heater (@bheater) March 24, 2018
I love Killer Mike.Thats my brother. He made some excellent points about Black gun ownership. The problem is, he is talking about it on the NRA platform & the NRA could give LESS THAN A DAMN about protecting Black people's 2nd Amendment rights.
