President Donald Trump has been raising questions by his dogged endorsement of an unproven treatment for the coronavirus -- and his motivations appear to be more financial than medical.

Trump admits he's not a doctor -- which, of course, he's not -- but MSNBC's Joe Scarborough and the Washington Post's Eugene Robinson are among many wondering whether the president is trying to boost the market for the antimalarial drug hydroxychloroquine.

Trump’s economic adviser, Peter Navarro, has been doing the media rounds to discuss the merits of science and medicine because there are very few scientists and medical experts willing to toe the Trump administration’s anti-science line when it comes to their novel coronavirus response. Navarro is the perfect mouthpiece for this administration in a time of crisis because he’s the kind of snake oil salesman that other snake oil salesmen try to avoid. As always, Fox News is a safe space for such bamboozlement.
