Personally I think the message was written by a staffer and not Trump. It was release because of what happened yesterday in an attempt to deflect criticism, and quite possibly without Trump’s knowledge or approval. And that Trump’s real thoughts will come out between now and the 20th.
Even during his speech yesterday he was reading off the teleprompter near the end, stopped and said, i don’t know about that one, it’s a nice statement but I’m not sure about that one. Trump obviously didn’t write this. We don’t even know where he is.
