LOADING ERROR LOADINGNBC News’ Kristen Welker on Wednesday asked Mehmet Oz — the former talk show host and heart surgeon who now runs the Centers for Medicare and Medicaid Services — about President Donald Trump’s repeated claim, mockingly dubbed “MAGA math,” that he’ll get pharmaceutical companies to lower drug prices by more than 100%. AdvertisementThen Welker asked Oz the obvious: “Cutting drug prices by 400%, anything over 100%, wouldn’t that effectively make them free? They’re equal, so it’s 100%.’”Welker pointed out that Trump has boasted about reducing drug prices by up to 1,500%. Oz fired back: “Well, if you take a drug that is $200 or $240 like we did last week and reduce it to $10, those are the numbers you’re talking about.”AdvertisementWhat? He then pivoted to talking about how important it was to reduce drug prices.
