"Of course President Trump is getting advice about the pandemic from Mehmet Oz, and of course Dr. Oz is eager to provide it. They’re a match made in ratings-obsessed heaven," says Frank Bruni. "Oz, mind you, is not a virologist. Not an epidemiologist. His actual specialty — cardiothoracic surgery — isn’t the most immediately relevant to the coronavirus. But his real specialty is using medicine as a means to maximum public exposure. He wasn’t about to let this dark chapter go to waste. Over recent weeks he has made a blizzard of appearances on Fox News, giving interviews to hosts not exactly known for the dissemination of responsible information. I mean Sean Hannity, Lou Dobbs, the Trump-besotted pep squad on Fox & Friends. And part of what the good doctor has done on these showcases is promote the anti-malarial treatment hydroxychloroquine as a potential wonder drug for Covid-19."
