Rev. Rick Warren talks with President George W. Bush at the Saddleback Civil Forum on Global Health in Washington, DC, on December 1, 2008.

Back in 1988, the World Health Organization and U.N. General Assembly first declared December 1 “World AIDS Day.” This year marks the 20th anniversary of the annual event dedicated to remembering those we’ve lost to the virus and to recommitting with vigor to the fight against AIDS.
