I believe that there is a twitter account @POTUS created by Obama. All President Trump would have to do is declare the @POTUS account to be the official (government) account and that @realdonaldtrump is his private account.
Done
Actually, I believe that the Democrat Party "judicial activist" judgetard already ruled on that, since President Trump uses his @realDonaldTrump account to make Presidential pronouncements.
The judgetard is a 74-year-old f*ckwit who probably has to have her grandchildren help her find the "On" button on her computer when she wants to use it.
I've seen people like her in the working world.
At her age and level of importance, she has "people" [Mundanes] for dealing with those magic boxes called computers.
Note that Judge F*ckwit doesn't have a Twitter account. Haven't checked, but I don't think she has a Facesucker account, either.
