It's true. From http://www.whitehouse.gov/news/releases/2006/12/20061201-2.html
The President Is Dedicated To Ending Discrimination Against People Living With HIV/AIDS
The President Will Direct The Secretary Of State To Request And The Secretary Of Homeland Security To Initiate A Rulemaking That Would Propose A Categorical Waiver For HIV-Positive People Seeking To Enter The United States On Short-Term Visas. The President considers the participation of people living with HIV/AIDS a critical element in the global HIV/AIDS response. A 1993 law prohibits HIV-positive people from receiving visas to visit the United States without a waiver. A categorical waiver would enable HIV-positive people to enter the United States for short visits through a streamlined process.
You beat me to it, glad I doublechecked before posting.
