The fragile foundation of evidence-based reality shoring up Donald Trump's life and presidency just got even more tenuous.

Trump's admission that he was dosing up on hydroxychloroquine, an unproven and possibly harmful therapy to ward off the coronavirus, appears to conflict with the codes of medical science and is a stunning development given his position.
"Here's my evidence: I get a lot of positive calls about it," Trump told shocked reporters when he made the disclosure about a malaria drug he has all but dispensed from the bully pulpit.
Trump's medical choices and the risks he chooses to take are his personal business. But he is not an ordinary citizen, and his use of the therapy sends a conflicting message to Americans told by the US Food and Drug Administration that it is not proven to work against Covid-19 and could be counterproductive.
