Rand Paul’s questions during a Senate committee hearing Tuesday and observed his demeanor as he repeatedly vehemently and angrily denied that NIH funding had been sent to the Wuhan Institute of Virology (WIV) for gain-of-function research or for any research on “this” virus, along with other emphatic denials, many of us thought Fauci may be protesting too much. If there was nothing untoward going on, “Why so nervous?” Well, we know one reason Fauci was so nervous is that the NIH’s involvement with gain-of-function research and the WIV is well documented, as we reported Thursday.
