Ding ding ding ding! Dr. Meng-li Yan was the source of the intelligence that lead to Trump banning travel from China against Fauci, Mnunchin and others' advice. She leaked to a US based Chinese blogger (Lude) on 1/19 regarding the severity of the epidemic. The message went from blogger -> Bannon -> Navarro -> Trump. She was also likely the source behind using hydroxychloroquine as a treatment -- Lude was also the first to tell the world to use hydroxychloroquine during early treatment.
