There had been some concern that Bill Clinton would not attend the graduation of the first class of the University of Arkansas Clinton School of Public Service. After all, he receives hundreds of graduation speech requests yearly, and the guy does stay busy promoting his AIDS and global warming issues and helping Democrats raise money. Really, how much time does he have? But his refusal to commit to being at the first graduation on December 13 was really starting to irk students at the Little Rock, Ark., school, our Suzi Parker heard. Well, she reports, everybody can rest easy now. The school's namesake will attend after all. But hurry up and get those graduation tickets. The Great Hall in Bubba's library isn't that big, and they don't plan to move the graduation to a larger venue.
