She apparently brought this up first in 2012 when Romney named him as a likely justice when he was running. It was debunked back then. The FBI has already said there is nothing to investigate. She doesn't remember when it happened, doesn't remember where it happened and there are no witnesses to either it occurring or either of them telling anyone. She supposedly remembered it in a therapy session for the first time after 30 years, but it has caused her pain and suffering ever since.
