The NBA is teaming up with former New York City Mayor Michael R. Bloomberg's Everytown for Gun Safety organization to help increase background checks for gun buyers, make stronger penalties for gun trafficking and banning of gun sales to convicted domestic abusers.

Stephen Curry headlines the NBA stars who will appear in an anti-gun violence ad during the league's Christmas Day games on Friday.

The PSA is directed by Spike Lee that will also feature other NBA stars like Carmelo Anthony, Chris Paul and Joakim Noah. Lee, a member of Everytown's council, is the one who proposed the campaign to ESPN president John Skipper last November, who in turn brought the idea to NBA Commissioner Adam Silver, per the New York Times.

The campaign is called "End Gun Violence" that focuses on the 88 Americans that die and hundreds who gets injured every day due to guns. The ad will air on ESPN and ABC's Christmas Day games with Grammy Award-nominated artist Andra Day, including gun violence survivors and relatives are also participating.

One of the survivors of shootings and relatives of those killed by guns include Andy Parker. His daughter, Alison, was the television reporter in Virginia that was shot dead in the middle of a live broadcast by a former co-worker.

Curry used his daughter, Riley, as a powerful example while Anthony spoke about growing up in Baltimore and New York. Paul talked about seeing gun violence incidents in New Orleans and Los Angeles. Noah, on the other hand, revealed that, while playing basketball in a park with some kids, he was approached by a young woman and told him that her brother was shot and killed on the same court he was playing a year earlier.

"I heard about a shooting involving a 3-year-old girl over the summer. My daughter Riley is that age. I don't know what I would do if I got a call if, you know, my daughter's gone. No parent should ever have to go through that," Curry said.

"You can go around the corner and get a gun. You can go to this person and get a gun. It's just too easy, too accessible. And it's going to be like that until we decide, as people, to fight against that," Anthony added.

President Barack Obama wrote on Twitter: "I'm proud of the NBA for taking a stand against gun violence. Sympathy for victims isn't enough. Change requires all of us speaking up." People can join the campaign using the #EndGunViolence.
