Bono Fights AIDS and Poverty

Bono, Puff Daddy, Georges Clooney, Justin Timberlake, Tom Hanks and Brad Pitt have one fight in common.    They're all participating in the Public Service Announcement, that started on April 10th, which aims to persuade the U.S. government to spend an additional one percent of its budget to assist Africa and other struggling regions. "This isn't a cause -- it's an emergency."
