I do this at work all the time.    If I can’t understand someone I tell them their voice is muffled and I have no idea what was just said.    I have not had a person yet NOT pull down their mask to speak.    Most people just do it on instinct.    The press know what their job is and how to keep up a presentation on camera.    That’s all it is. I guarantee if the person who asked that question was in his own office at a meeting they would pull down the mask and say it again.       ’s not about the mask but about the presentation.    The media are ordered to keep the COVID scare alive as it means $$$.
