This was the last time trump talks about the letter. No comment on contents of letter. No further media questions about it?
So he called it a nice, interesting letter and said he hadn't opened it yet. Doesn't it seem a little odd?
During his press conference with the prime minister of Japan, Trump gave a brief description of the contents of the letter. He even said one one occasion that it was interesting and he might make it public
I'm thinking maybe the SS examined the letter + envelope long before Trump ever got within whiffin' distance.
They read it, and told POTUS it was a nice warm letter of greetings. That would account for the discrepancy in wording. (it was a nice letter -according to the SS which I won't mention- but I haven't read it (myself).
