Lab chimps released after 30 years in cages
Animal rights activist and ‘True Blood’ star Kristin Bauer discusses the release of a group of chimpanzees who have spent the last 30 years in cages at a medical testing facility. The chimps who were injected with the HIV virus will live the remainder of their lives in an Austrian Sanctuary with freedom to be outside.
Bauer is a long time animal rights activist and supports banning all medical experimentation on chimpanzees.
