I'm not sure if Mr Trump will have continued access to Twitter when he is President.
This may be because his office prevents it, but it is certain that his 'people' will want to prevent it, since it provides an outlet for Mr Trump's dangerously ill-thought-out statements, rants, revenges, and similar nonsense not commensurate with his office and responsibilities.
The sooner the powers-that-be can get him releasing approved statements and sound bites, the better they will feel.
