You may be doing yourself a disservice. The 15 day concept was the work product of medical experts.
As the record shows the anti-MAGA's on both sides of the aisle were looking for even the flimsiest of reasons to shut Trump down and even get rid of him.

(Kemp didn't have such a worry and was probably encouraged by the anti-MAGA's to publicly defy Trump.)
“experts”, stopped right there.
