Meet the anti-mask Michigan "scientist" stoking the fourth wave

In a 22-minute video from April 15 that has been shared widely on Facebook, Kelly explains that she’s been denied entry to the public meeting despite what she says is a “medically recognized” disability and PTSD diagnosis that prevents her from wearing a mask. When another parent questions that explanation, she switches tack and launches into a “science”-based assault on masking. “I am actually an exposure scientist,” Kelly says to the other parent, who’s off-screen. “Oh, an exposure scientist,” the parent can be heard saying, as she laughs. “Yes, I’m an industrial hygienist, and I actually travel around the country testifying in front of governors. I’ve opened up Texas and North Dakota,” Kelly says.
