Sec. Esper is doing everything he can not to answer those very questions on FNC right now. He was charged with finding out if it was deliberate from a lab or from nature and his determination is it was natural. Somehow, the faster he speaks just to his meme an avoids the questions, the more unbelievable he becomes.
From what I can decipher from the virology reports coming out since Jan, there is nothing natural about this pathogen It is deiberately created to do the damage it is doing, and probably more damage in the future to its infected host. We are not being told.
