There's no evidence Dr. Fauci had anything to do with the beagle experiments, other than his association with the NIH ;

'Research conducted on behalf of NIAID is funded in large part through annual funds allocated by Congress and the president, though direct projects may be signed off on by various leaders within NIH. However, there is no evidence that the grant was personally approved by Fauci and there is no mention of him in the FOIA documentation. All that we can definitively say is that at least some of the money came from NIH."

I suspect most of the anti-Fauci stuff found on line is similarly sketchy, but I'm not interested in pursuing it further.
