Here is an interesting tidbit to add to yesterday's "honk" from the motorcade & adds to the @POTUS_Schedule consideration.
I have personally found the @POTUS_Schedule account interesting; it's clearly tied into things but whether it's "official" or not I/we don't know.
Backdrop here is that they posted a copy of their sign (I posted here last night on the kitchen table) to @POTUS_Schedule. That doesn't mean that @POTUS_Schedule got it and gave it to "Q" team - but certainly suggests that's something else that's in the picture + monitored too (at the least)
