That actually makes the most sense. Why would they want his every move made public?
They don’ t.
None of the available POTUS Schedules anywhere show everything.
None seem to show otherwise unknowable future scheduled events, if they show any “days away” future events at all. Any actionable info of that nature is likely disinformation.
They are all more of a log, than a schedule.
It seems only one Twitter based schedlue shows what could be a Trump Team professional level of Human Input. (The one Twitter points everyone to first.)
