President Bush on Friday said, "I'm proud of your character. I want to thank the Celtic organization for what you do off the court as well. I believe there is a huge responsibility not only to try to win on the court but to be responsible citizens in the community in which you live. The Shamrock Foundation, for example, helps disadvantaged children during the season and after the season. I appreciate the fact that during the second quarter of every home game, the Celtics honor some caring citizen; someone who I said is a soldier in the army of compassion. With the "Hero Among Us" program, that's a really good idea, and I thank you for doing that. I want to congratulate you for worrying about children and literacy and using your special status in society to set a good example." More Videos
