@Mame,
Well, it's inappropriate, especially in a photo news op, but who knows, really? We don't know all the details, like how long he'd known her and her husband. Were they friends? Was she his god-daughter? Was she friends with one of his kids?
I take more exception to Trump saying he can grab anyone's pussy if he has money.
And I also read that he's socially awkward anyway, so maybe it's more a function of that.
But... about those 6 year olds?
