Dr. Malone is quite new to the right-wing media world, first appearing regularly on podcasts in June 2022. His statements in late December on “The Joe Rogan Experience” were at the center of the uproar over Mr. Rogan’s role in spreading bad information about the virus. Dr. Malone earned a medical degree from Northwestern University in 1991, and for the next decade taught pathology at the University of California, Davis, and the University of Maryland. He then turned to biotech start-ups and consulting. He points to more frequently is from his time at the Salk Institute for Biological Studies in San Diego. Those experiments, he says, make him the inventor of mRNA vaccine technology. In recent months, he and his wife have made numerous stops at popular conservative conferences. Months ago, he was promoting the drugs hydroxychloroquine and ivermectin for treatment of Covid-19. Dr. Malone has more than 134,000 subscribers to his Substack newsletter. About 8,000 pay the $5 monthly cost, he said, which would amount to at least $31,200 in monthly revenue.
