Wait, wait, so, because a personal email address was
robinware456@gmail.com, that makes it his "alias?" Don't we all have those email / usernames thst we made for fun and look back upon as cringe.
I'm pretty sure zero people went around calling the engineer I worked with a decade ago "Captain Doobie 69" because that was his Hotmail account name and he used that address to send stuff from the field over the corporate email with his first.lastname@company.
Now, if Biden was going around calling people and telling them he was "John Barron," "John Baron", "John Miller" or "David Dennison," then that's pretty shifty. Luckily we have never had a narcissistic President do that before.
