Dude, there is no reason to wear a mask while on a video conference because the only viruses that travel through data cables infect computers, not humans. IOW, Quid Pro wearing a mask does absolutely nothing to protect or infect Xi or Putin. Quid Pro can wear a mask off-camera if it makes him feel better, then shoo everyone more than 6 feet away when on camera.That's an interesting theory, have run that one past anyone with a background in epidemiology ?Yes, because disease spreads through remote connections like virtual conferences.Probably something to do with those pesky scientists at the CDC recommending the wearing of masks by vaccinated individuals to help prevent them spreading the disease to others.
Someone would have to be an extremely poor leader to disregard the recommendations coming from his/her own subordinate organization (in this case the CDC falling under the authority of the Executive Branch).
Meanwhile, back in reality, rumor has it that more than one individual may be present traveling to and attending a site from which a virtual conference takes place.
