President Obama salutes NBA for 'taking a stand against gun violence'

President Obama tweeted his support for the NBA’s collaboration with a public service announcement against gun violence that featured Carmelo Anthony, Joakim Noah, Chris Paul, and Stephen Curry.

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.

The campaign is promoted by Everytown for Gun Safety, the nation's largest violence prevention organization in the country.
