Fauci has been threatened. By contrast, the president of Haiti actually was assassinated by people who didn't like that he would not kowtow to the global world order. Some see a connection to his opposition to covid vaccines.
ETA: The growing disgust with Fauci could also be the result of increasing coverage of his lies about having funded the engineering of a virus that has killed millions worldwide by funding gain of function studies in a Wuhan lab that didn't have proper safety protocols to prevent the virus from spreading into the community. I know many Republicans have brought this up including physicians like Rand Paul and Dr. Oz.
