Well...talk about the pressure of rushing the President's daughter (literally) - Barbara and Jenna Bush both come to mind. I suspect their recs were written by their mother, a Theta alumna, who was married to the POTUS at the time they went through rush. I imagine the Yale and Texas alumnae didn't blink. After all, it's Texas. It's Yale.
(ETA - thinking about LBJ's older daughter, a ZTA alumna - was her father in office when she rushed? Oh, this could be fun!)
