Dr. Anthony Fauci, former director of the National Institute of Allergy and Infectious Diseases, co-authored as many as 50 scientific papers with his former senior scientific adviser, David Morens, who has been embroiled in a scandal over the use of his personal email address for government business to avoid oversight during the pandemic.

The collaboration of nearly 30 years illustrates the depth of the relationship between Fauci and Morens despite Fauci’s efforts this week during congressional testimony to minimize their connection.
