WASHINGTON -- The "Je Suis Charlie" rally cry is making its way into the NBA.
"Je Suis Charlie" -- "I Am Charlie" in English -- has become a worldwide slogan to show solidarity with Charlie Hebdo, the Paris weekly newspaper where 12 people were killed Wednesday in a terrorist attack.
Seraphin was born in French Guiana and has represented France in international competitions. His family lives in Paris, and he texted his mother earlier Friday to make sure she was OK.
"Kind of insane what's going on right now 'cause we've never faced this type of thing," he said. "For sure, right now, it's a hard time for us."
Bulls forward Joakim Noah noticed the T-shirt and gave Seraphin an approving chest-tap at midcourt. Noah is the son of French tennis champion Yannick Noah.
"I'm happy he did that," Joakim Noah said. "[France is] going through some tough times right now, and he honored the people."
