evidence: "This virus has a cure, it’s called hydroxychloroquine, zinc, and zithromax. People want to talk about masks? Hello, no you don’t need a mask. There are those who don’t want to open schools. No, you don’t need to be locked down. There is prevention, and there is a cure," Stella said in her speech. [...] "Medically, that is simply not true," Cooper said, referring to Stella’s claim that HCQ cures Covid. "The most recent study published in New England Medical Journal was done on 500 patients across 55 hospitals in Brazil showed no benefit [to hydroxychloroquine] and instead revealed heart complications which can be deadly." [...] "Cooper and CNN falsely portrayed HCQ as ‘harmful,’ ‘dangerous’, ‘disproven’ and supposedly ineffective for the treatment of COVID19. In truth, [hydroxychloroquine] is an entirely effective medication for the treatment of COVID19, as proven by clinical results, the success of doctors who use it frequently in their practices," the lawsuit states.
