Very interesting if real. It has been pretty obvious there are multiple authors due to different writing styles. But we all thought the reactionary 'they are all poo poo head' type tweets were Trump himself, looks like he had help even on those.
Which is kind of disturbing because if they came from one of his communication staff, this means they were most likely reviewed and vetted, not just Trump being reactionary all the time. (ie thought went into the worst tweets).
