These @&$&s are pure evil. He started promoting it because of early anecdotes from doctors in other countries.
Minor friendly correction:
He started promoting it because of early published clinical research studies from well known expert doctors in other countries that showed strong statistically valid support for the treatment.
The French research report on their clinical trial, and other published clinical trials from China strongly support the use of hydroxychloroquine as a treatment for COVID-19.
The people saying the evidence was "anecdotal" are either lying, misinformed, or consider clinical trials "anecdotal" which is nonsensical. The trials may have been on limited numbers of patients, and they were open label, etc. but that doesn't make them any less reliable, particularly when the endpoints were based on lab measurements, not opinions or clinician observations.
Trump was elected partly because he is already very wealthy and can’t be bought off like past presidents. These people are idiots. Why does Trump need to make money off the cure. Insanity.
