We know of Durrant's interview by Tucker Carlson on FOX News.
I know that Tucker often directs Dr. Marc Siegel to look into medical issues that Tucker is interested in. I think that may be how Durrant ended up being interviewed by Tucker.
Now we see that Dr. Siegel himself has interviewed/examined President Trump. That interview aired today.
In the interview, Trump said that he did not get a shot of one of the medicines (in this context, Trump wasn't speaking of either remdesivir or regeneron), but rather that he got a transfusion of that medicine. The day after, he felt better than he had in 20 years.
The company has noted that a patient with ARDS had largely recovered the next day after being given lenz. I'm not saying THAT patient was Trump, this patient preceded Trump. But it demonstrates how quickly lenz provides relief to patients in respiratory distress, which Trump had.
Is dexamethasone administered through an IV? Do we know of any other drugs Trump received, that would have been delivered by IV?
These developments reinforce my speculation that Trump may have been given lenz, as I surmised.
