I hope they're right, because if they aren't, the federal strategy to deal with the virus was sidetracked by the president's TV habit.

It is bad that the president takes advice from his television.

It can work out or not in any specific case, but as a general practice and method of guiding federal policy, it is unstable and dangerous.

In this particular case, evidence for the benefits of chloroquine and hydroxychloroquine as a coronavirus treatment is mixed and anecdotal. But Trump's Fox advisers are telling him it's a surefire success, so he keeps pushing it.

Hopefully it works out, because federal energy going in to backing antimalarials isn't being used to pursue other potential treatments.

The mechanics here are virtually identical to any number of past Trump-Fox feedback loop cases.

Fox floats hydroxychloroquine as a cure --> Trump sees segments and promotes drug --> With Trump onboard Fox steps up promotion --> Trump keeps seeing segments and talking about it.
