My message to the graduate today is : ” Know your power and follow your passion — the power and passion that springs from the beauty of your dreams, the depth of your imagination and the strength of your values.” I have confidence that you will succeed because of the magnificent education you have received. at USF. I want to extend my congratulations to the class of 2007, wish you well and let you know you have a friend in the Speaker’s office. Thank you and God bless you.
美国永恒的青春气息是今天各位所展现出来的力量源泉，是这个世界希望的灯塔。美国的乐观、信仰和自信是她青春永驻。

今天我献给毕业生的寄语是：“了解你的实力，追随你的激情——源自于梦想的美丽、想象的深度和价值观的力量。”我坚信，有了在旧金山大学接收到的良好教育，你们一定能够成功。祝贺2007届的毕业生，祝一切顺利。请记住你们在众议院有我这个朋友。谢谢你们。愿上帝保佑你们。
