He's a delusional kook, but Collins is also a competent administrator, and I have to give him credit when he does the right thing.
The NIH, led by Dr. Collins, has recently accepted a recommendation from the National Institute of Medicine that future chimpanzee research funding shall be suspended, and that exceedingly strict guidelines are to be imposed.
They're just too close to us, and should fall under the penumbra of the same ethical considerations we apply to humans. I'd say the same of gorillas and orangutans…but I don't think there is any biomedical research being done on those animals, so the restriction would be unnecessary.
