evidence: The video was created by right-wing media outlet Breitbart. It depicts a group of people dressed in white lab coats — who call themselves "America's Frontline Doctors" — staging a press conference outside the U.S. Supreme Court in Washington. Those in the video claim that the anti-malaria drug hydroxychloroquine is "a cure for Covid" and "you don't need a mask" to slow the spread of coronavirus. "This virus has a cure, it's called hydroxychloroquine, zinc, and Zithromax," one of the women in the video claims. "You don't need masks, there is a cure." [...] Last month, the U.S. Food and Drug Administration announced it had ended the emergency use authorization of chloroquine and hydroxychloroquine, saying the drugs were "unlikely to be effective in treating Covid-19."
