No, he won’t speak and shouldn’t, The media will turn it into a circus claiming he is politicizing her death. He will be there, pay his respects and leave. They will also use it to demonize her to taint him by association. This is a no brainier. Anything he says about her should not be at the funeral. Just my opinion.
If I could write his script for response to the press going in and leaving the funeral, it would go something like this: “This is neither the time nor the place...”.
It’s yours free, DJT.
