There is literally no other reason to change the method of reporting except to undermine the CDC and hide the information from the public. Historians will look back at this dumpster fire of a presidency and it will not be kind to Republicans nor those in the cabinet. And they will wonder so incredbly hard why this insanity wasn't stopped using the 25th ammendment. (Not to mention the insanity of the Senate's adicating it's role as a check on the executive during the impeachment proceedings.)
