CNN asks Fauci why the scientific evidence consistently shows that masks do not work?

CNN:
"The most rigorous and comprehensive analysis of scientific studies conducted on the efficacy of masks for reducing the spread of respiratory illnesses — including Covid-19 — was published late last month.

Its conclusions, said Tom Jefferson, the Oxford epidemiologist who is its lead author, were unambiguous. There is just no evidence that masks make any difference. Full stop."

Fauci responds, "Yeah, but there are other studies."
