From NBC news:

A dozen doctors delivered speeches in front of the U.S. Capitol on Monday to a small crowd, claiming without evidence that the coronavirus could be cured and that widely accepted efforts to slow its spread were unnecessary and dangerous.

It was the latest video to go viral from apparent experts, quietly backed by dark money political organizations, evangelizing treatments for or opinions about the coronavirus that most doctors, public health officials and epidemiologists have roundly decried as dangerous misinformation.
