Why lie?
Along the lines of Hillary's (btw, she was never president, so I got that going for me...) landing under fire BS story, our duly elected (say, why is DOJ, et al, fighting so hard to interfere/slow roll the Maricopa County election audit?) President had to tell a lie about Amtrak, his mother, a conductor...

TLDR version: Biden, promoting Amtrak, recounts how as VP, he'd take Amtrak to see his ailing mother and a long-time conductor would pinch his cheek, and say, "Joey, baby!" to congratulate him on a million plus miles on Amtrak.and that the Secret Service had a fit the first time.
A. Biden's mother died in 2010 and the story is circa 2013-ish according to Biden.
B. The conductor retired in 1993.
Dementia means never having to get your story straight.
But at least he's not tweeting meanly.
