This needs to be brought up at her hearing.
If it is true. Not everyone that tweets is honest. I doubt that Fakebook would want to cooperate and expose her white-washed past profile IF it paints her in a negative light and proves she is nothing but apolitical opportunistic liar.
OTOH, if her prior online history revealed that she was truly a victim of the event she stated had happened, she would likely had left it up as evidence of her truthfulness.
As it stands with her accusations, there is nothing but verbal hearsay that predates Judge BK’s nomination made this year.
