The New Yorker's copyeditor, Andrew Boynton, copy edits Donald Trump's Black History Month speech and his speech at the National Prayer Breakfast. My surprise here is that most of these oddities are written into his speeches rather than from him directly based on the way he speaks (or non-reads). I mean, doesn't he have a speech writer? I would hope so. But at this point, I don't even think it would matter.
