My take on this -
Trump is signalling he is seeing the great work being done to recuperate the rescued children.
They were in bad shape but in 6 months have made amazing recoveries. The "before and after" shots will look shock the world when finally broadcast.
The "Plague" is child trafficking.
With all this great news he is feeling well
None of this, of course, has to do with the fake covid plandemic
Trump is somewhere else (well secured and insulated) and not at Walter Reed Medical Center
