The Lakers players wore the shirts during pre-game warmups before their game against the Sacramento Kings on Tuesday night in Los Angeles.
"I think if we ever lose the courage to be able to speak up for things that we believe in, I think we really lose the value that our country stands for," Bryant said after the game, via The Associated Press. "It's important that we have our opinions. It's important that we stand up for what we believe in. We all don't have to agree with it, and that's completely fine. That's what makes this a beautiful country."
The official Twitter account of the Lakers shared a photograph and video of Bryant and his teammates wearing the T-shirts during warm-ups.
