So... Mixing up foreign names means he doesn't know where a border is?
Does that mean that if you mix up your coworker's name, you don't know where you work?
What name did he mix up?
What does my coworker have to do with the border?
The Egyptian and Mexican leaders. As your link states.
He only mentioned one name. In the same press conference where he was scolding the special counsel who stated the reason why he wasn't charged with lying about and mishandling classified documents was because he was (effectively) senile and he doubted he would be convicted.
I mean, the reason why he wasn't charged is actually the same reason why none of the charges against Trump will ever result in anything of consequence and that is because these "special counsels" have no real standing under US Code to prosecute charges.
But Joe is senile, no doubt about it.
That "Corn Pop," fella is vicious, I tell ya...
