LeBron James #23 of the Cleveland Cavaliers takes the court against the Denver Nuggets at Pepsi Center on December 29, 2015 in Denver, Colorado.

*LeBron James has spoken publicly for the first time since a grand jury declined Monday to press charges against the police officers responsible for the November 2014 shooting death of Tamir Rice, a 12-year-old Cleveland native.

Activists have started the social media campaign #NoJusticeNoLeBron, calling on James to sit out games in protest of the grand jury decision.

Speaking to reporters Tuesday, James said he was slow to react to the news because he was not informed on all the details.

“For me, I’ve always been a guy who’s took pride in knowledge of every situation that I’ve ever spoke on,” James said following the Cavs’ win over the Denver Nuggets. “And to be honest, I haven’t really been on top of this issue. So it’s hard for me to comment. I understand that any lives that [are] lost, what we want more than anything is prayer and the best for the family, for anyone. But for me to comment on the situation, I don’t have enough knowledge about it.”

Activist and writer Tariq Touré created the #NoJusticeNoLeBron Twitter hashtag shortly after the grand jury’s decision was announced, calling for James to sit in protest of the outcome of the Rice case. The hashtag was embraced by Black Lives Matter activists and gained traction online.

James said that, just like the particulars of the investigation into the police officers’ actions against Rice, he was not fully informed about the calls for him to personally protest the lack of an indictment.

“I caught a little bit of it from my folks on the side saying that you guys might ask me about it, but I have no knowledge,” James said. “I’m not much of a social media guy. I’m on it, for sure, but I’m not always looking at what’s going on in it.”

A reporter later asked what James could do, as someone in his position, to help enact the social change he wants to see in this country.

“First of all, I think I’ve been very outspoken about what I believe in,” James said. “What hits home for me, what I am [knowledgeable] about. There’s been so many more issues that’s gone on that I haven’t spoken about.

“There’s been the San Bernardino massacre, there’s been guys going in movie theaters, shooting up movie theaters, there’s been other issues. Those are not something that … I don’t have much knowledge of so I don’t speak about it. So for me … if I feel like it’s something that I have a lot of knowledge about [I’ll add my voice to the issue], because I don’t like to speak when I don’t know about it.

“But I think the most important thing that we all need to understand, the most important thing, this issue is bigger than LeBron. This issue is bigger than me; it’s about everyone. And gun violence and tragedies and kids losing lives at a young age, some way, somehow we need to understand that that matters more than just an individual.”
