Can you provide context or possibly file a FOIA? I know this seem trivial, but it is not. If you were willing to contact Sidney or Lin or Trump team and give them the details about this call, then a FOIA could determine if they were indeed testing delivering packages marked later than received. Yes, in the case of the situation mentioned by op this does not directly apply. But I can think of several states that if this as working it does. Please at least take the trouble to contact the teams for this interaction as it may play significantly to ongoing cases.
