This is out in the area of @Stephen Sekula so all I can say is that it is an interesting story: https://www.nbcdfw.com/news/coronavirus/churchs-phony-covid-19-cure-sold-from-north-texas/2372339/
Yeah. Texas is a leading source of such nonsense. Many people who've misled the public and created health panic in the past call Texas home, which doesn't help. c.f. Andrew Wakefield (at least, as of 2018 he was a resident here... it's no accident).
This is why the fight to include science in policy decisions in Texas is so crucial. In TX, a B.S. degree holder, by law, can be considered a "scientific expert". This litters panels with people who have a shallow and wide education in science but no formal training in scientific research (which comes primarily from the Ph.D. process).
