Here, via twitter of course is Donald Trump’s explanation of why he tweets so much – complete with the a/are typo:
I use Social Media not because I like to, but because it is the only way to fight a VERY dishonest and unfair “press,” now often referred to as Fake News Media. Phony and non-existent “sources” are being used more often than ever. Many stories & reports a pure fiction!
That may or may not be an acceptable explanation to you. But, regardless, it is what Mr. Trump has to say on the matter.
Does he have a major point? A minor point? No point at all? Your call.
