Nice mis-type there John
Yes the "heavy twitting" Maybe if someone stuck all the furniture on the ceiling on the Oval Office, he'd walk around doing a handstand like a proper twit.
Obama's account was put on hold while he was in office, Tweets made from the POTUS account by Obama were signed 'BO' (His initials, obviously, although if you were to make fun of his initials, I guess Donny signing off DT might explain some of his slurped speech)
To get back to the original question though, Donald Trump is the President of the United States, words, tweets, emails sent while he is in Office are coming from the President of the United States and are official statements, its not like he has the "opinions are my own and do not reflect the opinions of my employers the American people (or President Putin - yes, I just put that in to wind up a few).
Anything else is just a poor attempt at smoke and mirrors to distance himself from something controversial down the line. I guess though if he is still using his unsecured Samsung phone, the Twitter app is long out of date and adding the @potus account instead might not work.
