A North Carolina high school teacher has been sent home for refusing to wear a mask as required by her school district. Aurora Preston, who teaches at South Johnston High School in Four Oaks, NC, said she had worn a face mask in the previous school year, but now doesn’t think they’re effective in slowing transmission of COVID-19, The News & Observer of Raleigh reported. Preston argues that it should be her constitutional right to decide whether to wear a face mask.
