Apparently he was given an experimental antibody treatment earlier today? Anyone have any more info on that?
EDIT (transcription of official release):
I release the following information with the permission of President Donald J. Trump.
Following PCR-confirmation of the President's diagnosis, as a precautionary measure he received a single 8 gram dose of Regeneron's polyclonal antibody cocktail. He completed the infusion without incident. In addition to the polyclonal antibodies, the President has been taking zinc, vitamin D, famotidine, melatonin and a daily aspirin.
As of this afternoon the President remains fatigued but in good spirits. He's being evaluated by a team of experts, and together we'll be making recommendations to the President and First Lady in regards to the next best steps.
First Lady Melania Trump remains well with only a mild cough and headache, and the remainder of the First Family are well and tested negative for SARS-CoV-2 today.
It's been pointed out that one of the requirements of the compassion program is that the patient be gravely ill and the drug is their only remaining option.
<speculation>
I do honestly wonder if that applies at his level. Could one of his doctors just requisition it? Would a company want to experiment on the president if it wasn't life or death?
</speculation>
I guess we'll know within a couple of days one way or the other.
(Although this, of course, is Donald Trump; pretty easy for me to imagine that he just demanded it and it happened, regardless of whether or not it was warranted or fully considered.)
According to my local newspaper it is REGN-COV2: https://www.regeneron.com/covid19 . It appears to be a synthetic replication ment to mimic antibodies from humans covid survivors.
