Ugh, this is horrible. One would have to wonder the medical data value of torturing poor doggies, this seems this highly unethical experimentation reveals little that you could not learn from... not live puppies.
I hope this causes real change into animal experiments in international medical research. If it can't be done ethically in the US, it should not be funded elsewhere.
Lying about masks? No problem.
Lying about "Gain of Function" research? to the point of redefining the terms in a pathetic attempt to kick the can a few more days? ... no problem.
ZOMG he's been Cruel to Puppies hang him!
