Speaking to MSNBC host Chris Haye Thursday night, Fauci called on Fox to take disciplinary action against the journalist.
The journalist met backlash Monday after she compared the chief White House Medical Adviser to Josef Mengele, a Nazi doctor whose grisly experiments on Jewish concentration camp victims throughout World War II earned him the chilling moniker "Angel of Death."
"It's an insult to all of the people who suffered and died under the Nazi regime in the concentration camps," Fauci, 80, fumed on Hayes' primetime political commentary program All In.
"I mean, it's unconscionable what she said."
"What I find striking, Chris," the irate immunologist continued, "is how she gets no discipline whatsoever from the Fox network."

"How can they let her say that with no comment and no disciplinary action? I'm astounded by that!"
Logan, 50, slammed Fauci Monday through a Fox News Primetime discussion regarding the Biden administration's answer to the new super-mutated Omicron COVID-19 variant.

The televised discussion with the journalist whose career took a hit in 2013 when a 2012 report on the Benghazi attack from the then-CBS correspondent was revealed as false, suggested her insight on the emergence of new Omicron variant after host Pete Hegseth, a known critic of coronavirus vaccine mandates and masking policies, blamed the Biden Administration for overhyping the still primarily unknown strain.

"There's no justification for putting people out of their jobs or forcing mandates for a disease that's ultimately very treatable, it's cheap to treat, medicines are available all over the world, and it has death rates that compare very much to seasonal flu," Logan announced throughout the Monday night talk.
The South African journalist, who joined Fox last year, set her sights on Fauci and made the contentious comparison.

"In that moment, what you see on Dr. Fauci, what people say to me, is that he doesn't represent science to them."
"He represents Josef Mengele – the Nazi doctor who did experiments on Jews during the second world war and in the concentration camps."

Logan went on: "I'm talking about people all across the world who are saying this."
"The response from COVID," she went on, "what it has done to countries everywhere, what it has done to civil liberties, the suicide rates, the poverty - it has obliterated economies."

"The level of suffering that has been created because of this disease is now being seen in the cold light of day, i.e., the truth - and people see that there is no justification for what is being done."
The remarks provoked an immediate backlash from a slew of social media users and organizations aligned against anti-Semitism, like the Anti-Defamation League and American Jewish Committee - both demanding apologies from the firebrand journalist.
