Asked about using chloroquine for this, Trump says, "Why should we be testing it in a test tube for a year and a half when we have thousands of people that are very sick, very, very sick, and we can use it on those people?" (Clinical trials are not done via "test tube"...)

Trump calls the evidence for chloroquine's effectiveness here "very strong evidence." Fauci says it's "anecdotal." (Trump notes trials are starting in New York.)
