This tweet is written as parody, but it seems self-evident from reading Trump's tweets that they do not all come directly from the president himself. Most political offices delegate social media to an internal team, presenting as if from a unified "source" when really they speak for an organization. Given the fierce competing factions within the administration - and the sort of kreminology political reporting has been reduced to in the current environment - this is precisely the kind of modern situation where textual analysis is helpful in determining who is speaking.
