There were four results if you search POTUS schedule on Twitter I posted them above.
I don’t doubt that it is the president schedule but I have not seen confirmation that it isn’t just posted to Twitter like anybody could do.

This trick is to search within Twitter’s internal search.
That way you get who Twitter thinks is POTUS Schedule.
And you get this:
https://twitter.com/search?q=POTUS%20Schedule&src=typd
And, if you search using Twitter’s “Search Twitter” function
and ask for Donald J. Trump Schedule, What do you think you’ll get.
This:
https://twitter.com/search?q=Donald%20J.Trump%20Schedule%20&src=typd
This is not Rocket Science.
Do you think Twitter doesn’t know where to send you when you ask it specifically for POTUS Schedule, or Donald J. Trump Schedule?
You might get extra results with a google Search, or Bing search or DuckDuckGo Search, but why would you think Twitter itself doesn’t know where the real one is and send you there?
