Ken & Rosie: Debate rages over lab chimps

02:52

Rock Center received unprecedented access to the Texas Biomedical Research Institute in San Antonio, Texas where chimpanzees are being experimented on to find a cure for Hepatitis C, a potentially deadly virus affecting four million Americans. Scientists at the lab say that testing on chimpanzees saves human lives.  But world-renowned primatologist, Dr. Jane Goodall, says that testing on chimps is morally wrong, and that it's time to retire these chimps to a sanctuary.  To see what retirement looks like, Rock Center visits the National Chimpanzee Sanctuary in Louisiana, Chimp Haven. NBC News Senior Investigative Correspondent Lisa Myers’ full report airs Monday, Jan. 30 at 10 pm/9c on NBC’s Rock Center with Brian Williams.
