They write:

In fact, it is not unreasonable at this time to conclude that surgical and cloth masks, used as they currently are, have absolutely no impact on controlling the transmission of Covid-19 virus, and current evidence implies that face masks can be actually harmful. All this to say and as so comprehensively documented by Dr. Roger W. Koops in a recent American Institute of Economic Research (AIER) publication, there is no clear scientific evidence that masks (surgical or cloth) work to mitigate risk to the wearer or to those coming into contact with the wearer, as they are currently worn in everyday life and specifically as we refer to Covid-19.
