September 11?

I've got this vague notion that somebody did something some years back on this date, but I can't quite put my finger on it . . . Was it that Ilhan Omar married her own brother, Ahmed Elmi? No, that's not it, not the sort of dating that leads to marriage. If that had happened, I'd remember it, for sure. No, it was something less invasive than specula on which celebrity is fooling around with which other celebrity. Somebody jog my memory, please . . .
