White House coronavirus adviser Dr. Anthony Fauci has told Kentucky Senator Rand Paul “You don’t know what you’re talking about,” after Paul accused him of lying about his alleged role in controversial virus research in China.

Questioning Fauci during a Senate Health Committee hearing on Tuesday about the government’s coronavirus response, Sen. Paul (R) implied that Fauci lied to Congress in May when he said that the National Institute of Health (NIH) did not fund so-called ‘gain-of-function’ research at the Wuhan Institute of Virology in China, believed by many to be the source of the coronavirus pandemic.

“I have never lied before the Congress, and I do not retract that statement,” Fauci replied.

Paul presented a 2015 academic paper that asserts such research did take place at the Wuhan lab, and was partly funded by the NIH. One US scientist has reviewed the paper and concluded that the research within “seemed to meet the definition of gain-of-function,” — but that it did not lead to the creation of the novel coronavirus. The term ‘gain-of-function’ refers to modifying and increasing the transmissibility of animal viruses to better study their effect on humans.

“This paper that you’re referring to was judged … up and down the chain as not being gain-of-function,” Fauci responded, before Paul interjected.

“You take an animal virus and you increase its transmissibility to humans, you’re saying that’s not gain-of-function?” Paul asked.

“That is correct, and Senator Paul, you do not know what you are talking about, quite frankly, and I want to say that officially,” Fauci snapped back. (RT)
