He warned against making Fauci 'untouchable' in an interview with Fox & Friends, claiming it would throttle debate outside of the doctor's own 'edicts and mandates.'
Republican lawmakers have been blasting Fauci this week over an interview he gave to CBS on Sunday during which he dismissed GOP criticism of him and his work as lies and opposition to science.
The scientist also claimed Republicans are using him as a 'scapegoat' to shield from anger at Donald Trump.
'It's sort of a way of ending all debate because if you attack him or have any debate over any of his edicts or his mandates, you're attacking science,' Paul said on Tuesday.
'But this is a very, very dangerous sort of idea. The idea that a government bureaucrat represents science and that he is now untouchable - that it is sort of like you are now contradicting the all high priest of science, if you say anything.'
The physician-turned-senator accused Fauci of 'deflecting' when confronted about his scientific beliefs.
'But there are real questions and there's real areas of science that he's never really debated because he deflects. And the thing is, there's never been a debate because he's the all-powerful scientist. You're not to question him, just do as you're told,' he said.

Paul then mocked Fauci by comparing him to the Wizard of Oz.
'Dr. Fauci says he is the all-powerful Oz, and we shouldn't question him. That's a real problem in a free country,' he said.
Fauci and Paul frequently clash when brought face-to-face at Congressional hearings. Paul often criticizes Fauci during television and radio appearances.
Paul was one of two Republican senators Fauci criticized by name during his sit down with news anchor Margaret Brennan.
'My job has been totally focused on doing what I can with the talents and the influence I had to make scientific advances to protect the health of the American public,' Fauci had said when asked about the criticism and threats his public role in the pandemic got him.
'So anybody who spins lies and threatens and all that theater that goes on with some of the investigations and the congressional committees and the Rand Paul's and all that other nonsense, that's noise.'
The other GOP lawmaker name-checked during the interview was Senator Ted Cruz of Texas, who at a recent hearing told Attorney General Merrick Garland to investigate Fauci over allegedly lying to Congress.
