SO WHAT?
If this country has another crisis like 9/11 or a terror attack, what flash cards will Joe reach for then to tell him what to do?
Does Jill have a carry case to keep all of Joe's cue cards organized in alphabetical order?
If Trump were caught needing flashcards, especially for such an important meeting as this, or for anything, the Left would declare him incompetent, dangerous and the laughing stock of the world and Nancy would need to call a hearing to consider the 25th amendment, which Joe is.
That so what.
