Circumstantial evidence, not conclusive either way, but clearly the Biden administration feels the evidence is weighted slightly more on the side you just called a conspiracy theory.
Which again, is all they allege for ebola, but unlike the co-author of that first paper I linked, I don’t have a PhD in virology, so what do I know.
Is the Biden administration lead by conspiracy theorists as well?
Again, inclusive and circumstantial, but pretty far removed from crackpot conspiracy theories and tinfoil hats.
