Caroline Kennedy referenced in her speech an address given by her father at AU. For those not aware, it was the June 1963 commencement address, and is one of the top 100 speeches according to this website: http://www.americanrhetoric.com/spee...tyaddress.html
I'm sorry my son wasn't there for yesterday's event! His graduation speaker last May was David Gregory, Chief White House correspondent for NBC and an alum of AU. At some point in his 4 years at AU he also heard Gorbachev speak. Exciting stuff!
